- Description:
- This database table is derived from the Swift TDRSS messages sent on ground soon after a BAT trigger occurs on-board. For each trigger there are associated up to 14 messages, however not all are always generated and sent on ground. The messages are generated on board by the BAT, XRT and UVOT instruments and the Figure of Merit part of the observatory's autonomy. The BAT and XRT can each have five different message types. The UVOT and FOM can each have two different message types. These TDRSS messages are the results of the on-board data processing of the three instruments and some contain data products. They are first distributed via the GCN and later archived. The BAT messages are: alert, 'ack' containing the position, or 'nack' if the position could not be calculated, a lightcurve and scaled map. The XRT messages are: centroid containing the position, an image (if the position has been calculated), centroid error if the position could not be calculated, spectra in Low Rate Photodiode and Windowed Timing modes, a lightcurve. The UVOT messages are: finding chart containing star positions and a subimage centered on the XRT position. The FOM messages are used to indicate if the FOM will or will not observe the new target and if the spacecraft will (or will not) request a slew for the new target. The parameters in this database table are a collection of high level information taken from the following messages : the BAT alert, 'ack' or 'nack' message, the FOM messages, the XRT position and image. If the information is not available the fields are left blank. All messages are provided as data products within this database table. 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 .

- Swift UVOT Instrument Log
- Short Name:
- SwiftUVOT
- Date:
- 07 Mar 2025
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The UVOT runs only one type of configuration filter/mode/window in a given time interval. This database table, therefore, contains for a given time interval a single record that describes one configuration. This database table is generated by the Swift Data Center. During operation, it is updated on daily basis. This is a service provided by NASA HEASARC .

- Swift XRT Instrument Log
- Short Name:

- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The XRT runs only one type of configuration mode/window in a given time interval. The table therefore contains for a given time interval a single record that describes one configuration. A new record is generated when the following is changing within an observation: new operating mode , new pointing mode, or new window configuration. This database table is generated by the Swift Data Center. During operation, it is updated on daily basis. This is a service provided by NASA HEASARC .

- NASA/GSFC HEASARC
- Description:
- This is the XMM-Newton Master Catalog and Public Archive table which has been created from information supplied to the HEASARC by the XMM-Newton Project. It is periodically updated as necessary. This database table contains the list of observations which have already been made by the XMM-Newton observatory, as well as those which are scheduled to be made in the near future (usually a a few weeks to a month ahead of the present). It does not contain observations which are scheduled to be performed further in the future, nor does it contain accepted observations which have not yet been scheduled. The list of all accepted XMM-Newton observations, including a number of ones which are unlikely to ever be carried out, such as accepted priority C targets, is available in the XMMAO Browse table. This table includes entries for both pointed data and for data obtained during spacecraft slews. The slew observations all have obsid values beginning with the digit 9 and, because they were not made at a fixed position, lack any positional information such as RA and Declination. Some XMM-Newton observations for which the archived data has become publicly available as indicated by the public_date parameter value, i.e., the proprietary period has expired, are not currently available at the HEASARC: such cases will have values of 'N' for the data_in_heasarc parameter. These datasets in most cases are available at the ESA XMM-Newton Science Archive (XSA) at <a href="http://nxsa.esac.esa.int/nxsa-web/">http://nxsa.esac.esa.int/nxsa-web/</a>. For much more detailed information on the XMM-Newton instruments and their operation, please refer to the XMM-Newton Users Handbook at <a href="http://heasarc.gsfc.nasa.gov/docs/xmm/uhb/">http://heasarc.gsfc.nasa.gov/docs/xmm/uhb/</a>. This database table was created by the HEASARC based on information supplied by the XMM-Newton Project at the following URLs: <pre> <a href="http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaobslog.txt">http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaobslog.txt</a> <a href="http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaslewlog.txt">http://nxsa.esac.esa.int/ftp_public/heasarc_obslog/xsaslewlog.txt</a> <a href="https://xmm-tools.cosmos.esa.int/external/xmm_mission_plan/odf_pps/catstrip.shtml">https://xmm-tools.cosmos.esa.int/external/xmm_mission_plan/odf_pps/catstrip.shtml</a> </pre> It is periodically updated within a few days of whenever these XMM-Newton Project's URLs are modified.

- XRISM Master Catalog
- Short Name:
- XRISMMASTR
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The X-Ray Imaging and Spectroscopy Mission (XRISM) is an international mission led by Institute of Space and Astronautical Science (ISAS) of Japan Aerospace Exploration Agency (JAXA). XRISM was launched on 2023 September 6 (UT) into a near-circular orbit with an apogee of ~575 km, an inclination of ~31 degrees, and an orbital period of about 96 minutes. During the performance verification (PV) phase, targets selected by the XRISM science team are being observed. Subsequently, it will become a general observatory with annual call for proposals open to all astronomers. XRISM has two co-aligned instruments that are used concurrently: Resolve, a soft X-ray spectrometer, and Xtend, a wide field-of-view imager. Resolve uses an X-ray microcalorimeter with ~5 eV spectral resolution withs a 3x3 arcmin field of view. It is currently operating with the Gate Valve closed, which limits its effective bandpass to 1.7-12 keV. Xtend is an X-ray CCD instrument with a 38 x 38 arcmin<sup>2</sup> field of view. This table contains a list of observations that have taken place as well as those that have been accepted and planned. The latter includes pre-approved targets for TOO observations and priority C targets whose observations are not guaranteed. This database table is based on information supplied by the XRISM Science Data Center at NASA/GSFC. It is updated automatically on a regular basis. This is a service provided by NASA HEASARC .

- XTE Master Catalog
- Short Name:
- RXTE
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table was created for the purpose of providing a comprehensive, accurate, and easily accessible tracking of Rossi X-Ray Timing Explorer (RXTE) pointed observations. It does not list observations made during slews: those are listed in the <a href="/W3Browse/xte/xteslew.html">XTESLEW</a> database table. The XTEMASTER table includes both observations that have already completed and those still scheduled to be done. The XTEMASTER table is regenerated automatically on a quasi-regular basis whenever the RXTE Science Operations Facility (SOF) updates their short-term or long-term schedules and transfers the new version(s) to the HEASARC. At that time, it will also incorporate all the latest information on which targets have been observed (using the daily RXTE ObsCats at <a href="https://heasarc.gsfc.nasa.gov/FTP/xte/timelines/obscat/">https://heasarc.gsfc.nasa.gov/FTP/xte/timelines/obscat/</a>) and which observations have been archived in the public RXTE Data Archive at <a href="https://heasarc.gsfc.nasa.gov/FTP/xte/data/archive/">https://heasarc.gsfc.nasa.gov/FTP/xte/data/archive/</a>.

- XTE Target Index Catalog
- Short Name:
- RXTE
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Rossi X-ray Timing Explorer (RXTE) Index table was created for the purpose of providing a concise and easily accessible tracking of RXTE observations, both those already completed and those still scheduled to be done. Each entry in this table corresponds to a specific proposal/target combination or `complete observation', in contrast to the RXTE Master table in which each entry corresponds to a specific proposal/target/ObsID combination or `observing segment'. A complete observation can consist of many (in some cases dozens) observing segments. This is a service provided by NASA HEASARC .
