- Einstein IPC Unscreened Photon Event List
- Short Name:
- IPCUNSCRND
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table gives access to the IPC unscreened data set, which includes files in the event list format together with auxiliary files. This data set was generated by the Einstein Data Center and delivered to the HEASARC on CD-ROM. The Einstein Observatory (HEAO-2) operated from November 1978 to April 1981. Einstein carried the first fully imaging X-ray telescope in space and operated in pointing mode. The Imaging Proportional Counter had a bandpass of 0.2-3.5 keV and was one of two detectors onboard used for imaging. During the Einstein lifetime more than 4000 targets were observed with the IPC. This database table was last updated by the HEASARC in August 2005. Galactic coordinates were added and some parameters were renamed to adhere to the HEASARC's current parameter naming conventions.

- Title:
- Einstein MPC Raw Data
- Short Name:
- MPCRAW
- Date:
- 10 May 2024
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Einstein Observatory (also known as HEAO-2 or HEAO-B) was operational from 1978 November 13 until 1981 April 25 when the Einstein attitude control system failed. The Monitor Proportional Counter (MPC) was a non-focal plane instrument that monitored the 1 to 20 keV X-ray flux of the source(s) being observed simultaneously by the operational focal plane instrument. The MPC was a collimated proportional counter filled with argon and carbon dioxide. It had a circular field of view, 1.5 degrees in diameter (FWHM), which was co-aligned with the telescope. A 1.5 mil Be window sealed the gas in the detector and shielded the detector from ultraviolet radiation. The active area of the MPC was 667 square cm. The MPC obtained useful data from 1978 November 19 until 1981 April 17, with the exception of a 3-month period from 1980 Aug 27 to 1980 Dec 08 when operation was intermittent, due to Einstein Observatory attitude control problems. The characteristics of the MPC have been described in detail by Gaillardetz et al.(1979) and by Grindlay et al. (1980). One duplicate entry was removed from the HEASARC implementation of this catalog in June 2019. This is a service provided by NASA HEASARC .

- Einstein SSS and MPC Raw Data
- Short Name:
- SSSRAW
- Date:
- 10 May 2024
- Publisher:
- NASA/GSFC HEASARC
- Description:
- The Einstein Observatory (also known as HEAO-2 or HEAO-B) was operational from 1978 November 13 until 1981 April 25 when the attitude control system failed. The Solid State Spectrometer (SSS) was operated intermittently between 1978 December 1 and 1979 October 22. However, the cryogen cooling for the detector was used up by about 2 weeks prior to the date of this last observation, so that the last reliable observation of the SSS is considered to have occurred on 1979 October 03. The SSSRAW database accesses the raw SSS data (and the associated monitoring proportional counter, MPC, data), restored in FITS format at HEASARC from the original machine dependent format data set.

- Einstein SSS Spectra and Lightcurves
- Short Name:
- SSS
- Date:
- 10 May 2024
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This table is the Einstein Solid State Spectrometer catalog of observations and data products. It incorporates the most recent ice model that is described in the article on the SSS calibration by Christian, Swank, and White that appeared in the HEASARC journal, Legacy, No. 1. Also available as "associated" data products are the quasi-simultaneous observations made by the Einstein Monitor Proportional Counter. There are 634 distinct SSS observations in this database, 95% of which have associated MPC data products. The remaining SSS observations cover time intervals in which all MPC data was flagged as bad by the pCHIP program that was used to generate the MPC spectra and lightcurves.

- eROSITA Observations Master Catalog
- Short Name:
- EROSMASTER
- Date:
- 10 May 2024
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This is the eROSITA Master Catalog which has been created from information supplied to the HEASARC by the <a href="https://erosita.mpe.mpg.de/edr/eROSITAObservations/">eROSITA-DE</a> team. This database table contains the list of observations made by the SRG eROSITA mission. Currently, the German eROSITA Consortium (eROSITA-DE) has made public the observations obtained during the Calibration and Performance Verification (Cal-PV) program for which it holds data exploitation rights. Over one hundred individual pointing and field scans were performed with eROSITA as a prime instrument between mid-September and mid-December 2019 form part of the Cal-PV program. For practical purposes, the eROSITA-DE team has divided the Cal-PV observations into four categories: <pre> Survey fields: These are scan observations of large, contiguous areas of the sky. Magellanic Clouds: These are observations around the Small and Large Magellanic Clouds. Galactic fields: These include observations with |Galactic latitude| < 17 deg. Extragalactic fields: These include observations with |Galactic latitude| > 17 deg. </pre> The HEASARC has created this database table, based on the observations from the shared public data, and added links to associated <a href="https://heasarc.gsfc.nasa.gov/db-perl/W3Browse/w3table.pl?MissionHelp=srg-erosita">eROSITA</a> catalogs and data products, where available. The HEASARC produced this database table based on information obtained from the eROSITA-DE website in July 2023. This is a service provided by NASA HEASARC .

- EUVE Archive and Observation Log
- Short Name:
- EUVE
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This catalog of the EUVE Science Archive has been constructed based on information provided by personnel of the Center for Extreme-Ultraviolet Astrophysics (CEA), and is made available in the current EUVEMASTER database table. Most of the information in the catalog is also in the headers of the FITS files. The HEASARC now has nearly all of the 1378 pointed EUVE Deep Survey/Spectrometer (DS/S) datasets that were processed by CEA until its closing in March 2001. There are a small number of observations that were made in the year 2000 for which the HEASARC does not currently have the corresponding datasets. Notice that this catalog does not contain entries corresponding to EUVE observations in scan mode or where the files received by the HEASARC were not of the normal image or events type. This is the 7th (and possibly final) version of the EUVEMASTER database, last updated in June 2001. This catalog has been constructed based on information provided by staff members of the Center for Extreme-Ultraviolet Astrophysics (CEA) in Berkeley, CA, whose help is gratefully acknowledged.

- EXOSAT Bibliography
- Short Name:
- EXOPUBS
- Date:
- 10 May 2024
- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table contains information about all EXOSAT publications in refereed journals that make use of EXOSAT data. Each entry is unique for every combination of publication and X-ray source. For example, a paper which discusses five X-ray sources will have generated five distinct entries in the database, each referring to a different X-ray source. Unlike EXOLOG, the EXOPUBS database also includes entries for serendipitous sources. In addition to standard database parameters such as source name, coordinates, object class, etc., the EXOPUBS includes the full reference (authors, journal, volume, page, year) and title of each publication. Note the information is not complete after the year 1991. This is a service provided by NASA HEASARC .

- EXOSAT CMA Images for Each Pointing
- Short Name:
- CMAIMAGE
- Date:

- Publisher:
- NASA/GSFC HEASARC
- Description:
- This database table contains the images from two EXOSAT LE telescopes with the channel multiplier array (CMA) detectors in the focal plane. The CMA/telescope combination covers the 0.05-2.5 keV energy range with a field of view of 2 degrees and an on-axis angular resolution of 24 arc seconds (HEW). The detectors had no intrinsic spectral capabilities; however, different filters were used to make broad band measurements. The most commonly used were Thin Lexan (number 7), Aluminum-Parylene (number 6) and Boron (number 8). An image was generated for each filter used during an observation. This Browse table was created in March 1995 and updated in October 2003. This is a service provided by NASA HEASARC .
