The HETE2TL database table records the pointing direction of the HETE-2 boresight camera and the roll angle of the HETE-2 spacecraft at each given time, as determined by the aspect camera/optical sub-system aboard HETE-2. HETE-2 (the High Energy Transient Explorer) is an international mission designed to help unravel the mystery of Gamma-Ray Bursts (GRBs). The primary goal of HETE-2 is to determine the origin and nature of cosmic gamma-ray bursts (GRBs) by simultaneous observation of soft and medium X-rays and gamma-rays to provide precise localization of GRBs and identification of counterparts to these explosions. HETE-2 carries three science instruments: a set of wide-field gamma-ray spectrometers (FREGATE), a wide-field X-ray monitor (WXM, and a set of soft X-ray cameras (SXC) HETE-2 was launched on October 9, 2000, and declared fully operational on February 6, 2001. While this mission was active, this HEASARC database table was updated on a thrice-per-week basis, depending upon updates to the timeline file. The last update that was provided was in August 2006. Some duplicate entries were remove in June 2019. This is a service provided by NASA HEASARC .
This table records high-level information for the observations obtained with Hitomi. Hitomi was equipped with four different instruments that together cover a wide energy range 0.3-600 keV. 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 in 2016.
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 .
This is the HST Planned and Archived Exposures Catalog (PAEC) as obtained from the Space Telescope Science Institute (STScI) Archive which created the original compilation from their Archive and Proposal databases. This database table provides a summary of all approved HST observations, including already completed observations and those which are planned to be executed as part of the current cycle or are reserved for execution by Guaranteed Time Observer (GTO) programs for the upcoming cycles. This database table provides a summary of both planned and completed HST observations. Much more information can be obtained about each exposure, and the data themselves can be retrieved, using STScI's Multimission Archive (URL is <a href="http://archive.stsci.edu/hst/">http://archive.stsci.edu/hst/</a>) or STScI's Archive Web Interface (URL is <a href="http://archive.stsci.edu/hst/search.php">http://archive.stsci.edu/hst/search.php</a>). Note that a number of solar system and other objects have 0 values for their 2000 equinox RA and declination coordinates in the original HST table and hence also in this HEASARC database. This HEASARC version of the HSTPAEC will be updated on a regular basis, usually within one month of the data files on the STScI Web site (URL <a href="http://archive.stsci.edu/hst/paec.html">http://archive.stsci.edu/hst/paec.html</a>) being updated. This database table is recreated by the HEASARC on a routine basis, usually within one month of the PAEC data files at the STScI Hubble Data Archive (HDA) being modified.

The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope by
combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA)
into a single master catalog.
The Hubble Source Catalog (HSC) detailed search
displays an entry for each separate detection (or nondetection if nothing is found at that position)
using all the relevant Hubble observations for a given object
(i.e., different filters, detectors, separate visits).
The catalog currently contains over 100 million entries.

IceCube has performed several searches for point-like sources of neutrinos. The events contained in this release make up the sample used in IceCube's 10-year time-integrated neutrino point source search [1]. Events in the sample are track-like neutrino candidates detected by IceCube between April 2008 and July 2018. The data contained in this release of IceCube's point source sample shows 3.3 sigma evidence of a cumulative excess of events from a catalog of 110 potential sources, primarily driven by four sources (NGC 1068, TXS 0506+056, PKS 1424+240, and GB6 J1542+6129). NGC 1068 gives the largest excess and appears in spatial coincidence with the hottest spot in the full Northern sky search [1]. IceCube's 10-year neutrino point source event sample includes updated processing for events between April 2012 and May 2015, leading to differences in significances of some sources, including TXS 0506+056. For more information, please refer to [2]. This release contains data beginning in 2008 (IC40) until the spring of 2018 (IC86-VII). In order to standardize the release format of IceCube's point source candidate events, this release duplicates and supplants previously released data from 2012 and earlier. Events from this release cannot be combined with other IceCube public data releases. Please note that this dataset is dominated by background events from atmospheric muons and neutrinos detected by IceCube, with a subdominant astrophysical event contribution. Any spatial or temporal correlations should therefore be carefully evaluated on a statistical basis. See [1] and references therein for details regarding the statistical techniques used by IceCube.

This HEASARC database table contains the INTEGRAL pointed observing programs for AO-1 through AO-20 and includes targets in both the Core Program (Guaranteed Time) pointed observations list and in the General Program (Open Time) accepted observations list. The structure of this database table was last revised by the HEASARC in August 2007. It was updated to include AO-20 in November 2022. The contents of the table are automatically updated on a weekly basis using the referenced data obtained from the ESA INTEGRAL mission website at <a href="http://integral.esac.esa.int/">http://integral.esac.esa.int/</a>.

Because of the pointing-slew-pointing dithering-nature of INTEGRAL operations, each observation of a celestial target is actually comprised of numerous individual S/C pointings and slews. In addition, there are periods within a given sequence where scheduled observations occur, i.e., engineering windows, yet the instruments still acquire data. The INTEGRAL Science Data Center (ISDC) generalizes all of these data acquisition periods into so-called `Science Windows.' A Science Window (ScW) is a continuous time interval during which all data acquired by the INTEGRAL instruments result from a specific S/C attitude orientation state. Pointing (fixed orientation), Slew (changing orientation), and Engineering (undefined orientation) windows are all special cases of a Science Window. The key is that the same attitude information may be associated with all acquired data of a given Science Window. Note that it is possible to divide a time interval that qualifies as a Science Window under this definition into several smaller Science Windows using arbitrary criteria. The INTEGRAL Public Pointed Science Window Data Catalog is a subset of the INTEGRAL Science Window Data Catalog. It only includes pointed science windows that have non-private proprietary status and at least one instrument's "good" exposure time greater than zero. This database table was first created at the HEASARC in October 2004. It is a slightly modified mirror of the online database maintained by the ISDC at the URL <a href="http://isdc.unige.ch/index.cgi?Data+browse">http://isdc.unige.ch/index.cgi?Data+browse</a> <p> The HEASARC version of this table is updated automatically within a day of the ISDC updating their database table.
