111. Einstein SSS Spectra and Lightcurves
ID:
ivo://nasa.heasarc/sss
Title:
Einstein SSS Spectra and Lightcurves
Short Name:
SSS
Date:
07 Mar 2025
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. This is a service provided by NASA HEASARC .

Publisher:
NASA/GSFC HEASARC
Description:
These data are from the Compton GRO EGRET team. Data are from all pointings of the EGRET instrument in the verification phase and phase 1-4 of the Compton mission.

Title:
eROSITA All-Sky Survey Master Catalog
Short Name:
ERASSMASTR
Date:

Publisher:
NASA/GSFC HEASARC
Description:
The eROSITA-DE DR1 comprises data from the first six months of the SRG/eROSITA all-sky survey (eRASS1) whose proprietary rights lie with the German eROSITA consortium. Data rights are split by Galactic longitude (l) and latitude (b), with a division marked by the great circle passing through the Galactic poles (l,b)=(0,+90);(0,-90) and the Galactic Center Sgr A* (l,b)=(359.94423568,-0.04616002): data with -0.05576432&lt; l &lt;179.94423568 degrees (Eastern Galactic hemisphere) belong to the Russian consortium, while data with 359.94423568 &gt; l &gt;179.94423568 degrees (Western Galactic hemisphere) belong to eROSITA-DE. The Western Galactic hemisphere observations were released to the public through the &lt;a href="https://erosita.mpe.mpg.de/dr1/"&gt;eROSITA-DE site&lt;/a&gt; on 31 January 2024. In the Early Data Release (EDR), the data taken during the Calibration and Performance Verification (Cal-PV) phase were released and are available in &lt;a href="/W3Browse/erosita/erosmaster.html"&gt;EROSMASTER&lt;/a&gt;. The reprocessed EDR observations are not part of DR1. The primary data products of the eROSITA-DE DR1 consist of calibrated event files, which contain the information generated by the cameras used during the eRASS1 observations. The eSASS4DR1 pipeline creates these event files after the received telemetry data from eROSITA of each observation has been reformatted, packaged, and archived by a pre-processor. Note that the coverage of the sky is not uniform, i.e., not all observations have been performed with all seven eROSITA telescope modules (TMs). The eROSITA-DE team has divided the eRASS1 observations into 4700 sky tiles for practical purposes. Each sky tile has a size of 3.6x3.6 square degrees, overlapping by approximately 20 arcmin. Of the 4700 sky tiles, eROSITA-DE have proprietary rights on 2248 of them, and 199 sky tiles have shared rights between the German and Russian consortiums. eROSITA-DE DR1 comprises 2447 sky tiles in total, of which 199 have partial eROSITA-DE data. The FITS table here, provides the mapping between sky-tile identification and sky coordinates for the 2447 sky tiles. In addition, the 0.2-2.3 (&lt;a href="/W3Browse/erosita/erass1main.html"&gt;ERASS1MAIN&lt;/a&gt;) and 2.3-5 keV (3-band; &lt;a href="/W3Browse/erosita/erass1hard.html"&gt;ERASS1HARD&lt;/a&gt;) source catalogs are also available. This database table was created by the HEASARC in August 2024 based on the FITS file of the survey field boundaries available from the eROSITA-DE &lt;a href="https://erosita.mpe.mpg.de/dr1/AllSkySurveyData_dr1/"&gt;DR1 site&lt;/a&gt;.

Title:
eROSITA Observations Master Catalog
Short Name:
EROSMASTER
Date:
07 Mar 2025
Publisher:
NASA/GSFC HEASARC
Description:
This is the eROSITA Master Catalog which has been created from information supplied to the HEASARC by the &lt;a href="https://erosita.mpe.mpg.de/edr/eROSITAObservations/"&gt;eROSITA-DE&lt;/a&gt; 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: &lt;pre&gt; 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| &lt; 17 deg. Extragalactic fields: These include observations with |Galactic latitude| &gt; 17 deg. &lt;/pre&gt; The HEASARC has created this database table, based on the observations from the shared public data, and added links to associated &lt;a href="https://heasarc.gsfc.nasa.gov/db-perl/W3Browse/w3table.pl?MissionHelp=srg-erosita"&gt;eROSITA&lt;/a&gt; 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 .

Title:
ESO 1D reduced spectra
Short Name:
ESO SSAP
Date:

Publisher:
European Southern Observatory
Description:
The ESO Simple Spectral Access service provides access to the 1D reduced spectra generated either by the principal investigators of ESO observations, or by an unattended ESO processing-pipeline that makes use of certified master calibrations. The spectra are FITS files adhering to the ESO Science Data Product standard, based on the Virtual Observatory Spectral Data Model standard (v1.0 for some spectra, and v2.0 for some others, use the VOCLASS FITS keyword to discern the two).
119. EUVE Archive and Observation Log

Title:
EUVE Archive and Observation Log
Short Name:
EUVE
Date:
07 Mar 2025
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.

120. Evolution of Interstellar Dust
ID:

Title:
Evolution of Interstellar Dust
Short Name:
SAG-4
Date:
27 Oct 2022 19:00:00
Publisher:
NASA/IPAC Infrared Science Archive
Description:
The goal of the "Evolution of interstellar dust" guaranteed time key project (PI: A. Abergel & A. Zavagno) is to explore with Herschel the far-infrared (FIR) to submillimeter (submm) emission properties of dust particles in a wide range of regions within our Galaxy, from very diffuse clouds to sites of star formation and proto-stars. Photometric data taken with SPIRE and PACS are complemented with spectroscopy using the FTS of SPIRE and PACS to derive the physical conditions of the gas from the lines of [CI], the high-level rotational lines of CO, and the major cooling lines of [CII] and [OI].
