- Publisher:
- NASA/GSFC HEASARC
- Description:
- The ASCAMASTER table contains data on all ASCA observations that were ever in any of the following states: 'Accepted', 'Scheduled Long-Term', 'Scheduled Short-Term', 'Processed', and 'Archived'. The final status of an observation is given by the parameter Status. Specific dates that affect the status of an observation are listed as the parameters scheduled_date, observed_date, processed_date, archived_date, and cycle. Notice that, if one or more of the date parameters are empty for a given observation, this means that that those particular processes have not occurred: e.g., if observed_date is empty, this means that the planned observation was not observed.

- Chandra Observations
- Short Name:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table contains all of the observations made by the Chandra X-Ray Observatory (CXO, formerly known as the Advanced X-ray Astrophysics Facility or AXAF) as part of the Performance Verification and Calibration (PVC) phase and also contains all of the subsequent Cycles' Guaranteed Time Observers (GTO) and General Observer (GO) targets, and any Director's Discretionary Time (DDT) targets that have been observed. It also includes scheduled and as-yet-not-scheduled targets. The HEASARC updates this database table on a twice-weekly basis by querying the database table at the Chandra X-Ray Center (CXC) website, as discussed in the Provenance section. For observations whose status is 'archived', data products can be retrieved from the HEASARC's mirror of the CXC's Chandra Data Archive (CDA). The CXC should be acknowledged as the source of Chandra data. The PVC phase was during the first few months of the CXO mission; some of the calibration observations that are for monitoring purposes will be performed in later mission cycles. All calibration data (entries with Type = CAL in this database) are placed immediately into the CXO public data archive at the Chandra X-Ray Observatory Center (CXC); please see the Web page at <a href="http://asc.harvard.edu/">http://asc.harvard.edu/</a> for more information on the CXC data archive). GTO observations during Cycle 1 or any subsequent Cycle will probably occupy 100% of months 3-4, 30% of months 5-22, and 15% of the available time for the remainder of the mission. Guaranteed Time Observers will have the same proprietary data rights as General Observers (i.e., their data will be placed in the public CXC archive 12 months after they have received the data in usable form).

- Hitomi Master Catalog
- Short Name:
- HITOMASTER
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table records high-level information for the observations obtained with Hitomi and provides access to the data archive. The Hitomi mission was launched on a JAXA H-IIA into low Earth orbit on February 17, 2016, at 5:45 pm JPS from Tanegashima Space Center. Hitomi was equipped with four different instruments that together cover a wide energy range 0.3-600 keV. The Soft X-ray Spectrometer (SXS), which combined a lightweight Soft X-ray Telescope paired with a X-ray Calorimeter Spectrometer, provided non-dispersive 7-eV resolution in the 0.3-10 keV bandpass with a field of view of about 3 arcminutes. The Soft X-ray Imager (SXI) expanded the field of view with a new generation CCD camera in the energy range of 0.5-12 keV at the focus of the second lightweights Soft X-ray Telescope; the Hard X-ray Imager (HXI, two units) performed sensitive imaging spectroscopy in the 5-80 keV band; the non-imaging Soft Gamma-ray Detector (SGD, two units) extended Hitomi's energy band to 600 keV. On March 27, 2016, JAXA lost contact with the satellite and, on April 28, announced the cessation of the efforts to restore mission operations. At that time Hitomi was in check-out phase and had started the calibration observations. Data were collected from six celestial objects (Perseus, N132D, IGR_J16318-4848, RXJ1856.5-3754, G21.5-0.9, and Crab) as well as black sky for a total of about one month of data. The data from these observations were divided into intervals of one day if the observation of a specific pointing was longer that one day. A sequence number was assigned to each observing day and within data from all instruments are included. The day division was mainly to limit the data size within a sequence number. There are in total 42 sequences, and each record in this database table is dedicated to a single sequence. The early observations do not contain data from all instruments and in cases the object was not always placed at the aim point. This database contains parameters to indicate which instrument was on and if the celestial source was in the field of view. The SXS was the first instrument to turn on and therefore all observations contain SXS data, although the thermal equilibrium was reached after March 4 2016. The second instrument was the SXI followed by the HXIs and, finally, the two SGDs. This database table was generated at the Hitomi Science Data Center processing site (Angelini, L., Terada, Y, et al., 2016, SPIE 9905E, 14) with additions to indicate which instrument was on and if the source was in the FOV. It was ingested into the HEASARC database in June 2017. This is a service provided by NASA HEASARC .

- NuSTAR Master Catalog
- Short Name:

- NASA/GSFC HEASARC
- Description:
- The Nuclear Spectroscopic Telescope Array (NuSTAR) mission, launched on 2012 June 13, is the first focusing high-energy X-ray telescope in orbit. NuSTAR operates in the band from 3 to 79 keV, extending the sensitivity of focusing instruments far beyond the ~10 keV high-energy cutoff achieved by all previous X-ray satellites. The inherently low background associated with concentrating the X-ray light enables NuSTAR to probe the hard X-ray sky with a more than 100-fold improvement in sensitivity over the collimated or coded mask instruments that have operated in this bandpass. The observatory was placed into a 600-km altitude, 6 degree inclination circular orbit, and consists of two co-aligned grazing-incidence X-ray telescopes pointed at celestial targets by a three-axis stabilized spacecraft. NuSTAR has completed its two-year primary science mission, and, with an expected orbit lifetime of more than 10 years, the opportunity for proposing observations as part of the General Observer (GO) program is now available, with observations beginning in 2015. Using its unprecedented combination of sensitivity and spatial and spectral resolution, NuSTAR offers opportunities for a broad range of science investigations, ranging from probing cosmic ray origins to studying the extreme physics around compact objects to mapping micro-flares on the surface of the Sun. NuSTAR also responds to targets of opportunity including supernovae and gamma-ray bursts. This table contains a list of (a) unobserved targets that are planned or have been accepted for observation by NuSTAR in the future and (b) NuSTAR observations which have been processed and successfully validated by the NuSTAR Science Operation Center. The data from these observations may or may not be public and the user should check the value of the public_date parameter to determine the status of a specified data set. Only those ObsIDs which have a public_date in the past will have data publicly available. Observations with a public_date parameter value which is either blank or a date in the future have been ingested into the HEASARC archive but will remain encrypted until their public date. Entries with the status field set to 'accepted' are targets approved for scheduling, and the planned exposure time given in the exposure_a (and exposure_b) parameter will have a negative value for those targets. This database table is based on information supplied by the NuSTAR Project at Caltech. It is automatically updated on a regular basis. This is a service provided by NASA HEASARC .

- ROSAT All-Sky Survey Archival Data
- Short Name:
- RASSMASTER
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table contains the list German ROSAT All-Sky Survey observations which were obtained during the ROSAT All-Sky Survey phase (1990 July 30 to 1991 Jan 25) and which have become available to the public. These data were obtained in scanning mode and therefore an individual dataset covers a much larger area of the sky than do pointed moded observations. In addition all these data were obtained with PSPC-C, while all pointed mode observations after the end of the All-Sky Survey were obtained with PSPC-B. For each observation listed in this database table, the instrument used, processing site, and coordinates of the field center are given, as well as the ROSAT observation request number (ROR), actual exposure time, date the observation took place, and more. For details about the ROSAT instruments, consult the ROSAT Mission Description (NASA Research Announcement for ROSAT, Appendix F and its addendum) and the ROSAT GSFC GOF website at <a href="http://heasarc.gsfc.nasa.gov/docs/rosat/rosgof.html">http://heasarc.gsfc.nasa.gov/docs/rosat/rosgof.html</a> for more information.

- Description:
- This database table contains the list of all Röntgen Satellite (ROSAT) X-Ray Telescope (XRT) pointing-mode observations for which data sets are available, i.e., it excludes the ROSAT All-Sky Survey observations. Users should consult the RASSMASTER database table for those XRT observations which were made in scanning mode during the ROSAT All-Sky Survey (RASS) phase (30 July 1990 to 25 January 1991, and 3 August 1991 to 13 August 1991). For each observation listed in this table, parameters such as the focal-plane instrument used, the data processing site, and the target name and coordinates are given, as well as the ROSAT Observation Request (ROR) number, the actual and requested exposure times, the date(s) on which the observation took place, etc. For details about the ROSAT instruments, consult the ROSAT Guest Observer Facility (GOF) website at <a href="https://heasarc.gsfc.nasa.gov/docs/rosat/">https://heasarc.gsfc.nasa.gov/docs/rosat/</a>. A list of the available online ROSAT documentation can be found at <a href="https://heasarc.gsfc.nasa.gov/docs/rosat/rosdocs.html">https://heasarc.gsfc.nasa.gov/docs/rosat/rosdocs.html</a>. This table was created by the HEASARC in July 2004 by combining the data from two long-standing HEASARC Browse tables into one master table. It was updated by the HEASARC in March 2022 to add start and end times for the 157 sequence IDs which did not already have start and end times. This is a service provided by NASA HEASARC .

- Swift BAT Instrument Log
- Short Name:
- SwiftBAT
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The BAT can operate several configuration modes simultaneously. Each of the simultaneous modes is listed in separate records within this table. For a given time interval, there are several records (partially overlapping in time), each describing a single configuration/mode. The BAT modes collect data for the entire FOV but also have the capability to record rates (tag mask rate) for up to a few specific sky positions (typically 3) that correspond to a pre-assigned target ID. It is possible that at least two or more of these positions do not coincide with the BAT or NFI pointing position and therefore the target ID does necessarily coincide with Target_ID of the BAT or NFI pointing position. This table records for the position (RA and Dec) and Target_ID parameters the correct values associated to each of the mask tag data. This database table is generated at the Swift processing site. During operation, it is updated on daily basis. This is a service provided by NASA HEASARC .
