EROSMASTER - eROSITA Observations Master Catalog

Overview

This is the eROSITA Master Catalog which has been created from information supplied to the HEASARC by the eROSITA-DE 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:

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.

The HEASARC has created this database table, based on the observations from the shared public data, and added links to associated eROSITA catalogs and data products, where available.

Provenance

The HEASARC produced this database table based on information obtained from the eROSITA-DE website in July 2023.

Parameters

ObsID
The unique observation identifier for the eROSITA observation.

File_ID
The data products identifier containing the data for the eROSITA observation.

Name
The name of the target or field for the eROSITA observation.

RA
The right ascension of the eROSITA pointing, in degrees, given in the originating table in J2000 equinox with precision of 0.01 degrees.

Dec
The declination of the eROSITA pointing, in degrees, and given in the originating table in J2000 equinox with precision of 0.01 degrees.

LII
The galactic longitude of the eROSITA pointing. This has been derived by the HEASARC from the J2000 position.

BII
The galactic latitude of the eROSITA pointing. This has been derived by the HEASARC from the J2000 position.

Obs_Type
The observation type(s) are designated according to the following:

     C = Calibration
     P = Pointing
     S = Scan

Multiple types may be listed and are separated by a comma where applicable.

Category_Code
This code indicates the observational category code designated by the eROSITA-DE team. The meanings of these codes are as follows:

     E  = Extragalactic; observations with |Galactic latitude| > 17 deg.
     MW = Galactic; observations with |Galactic latitude| < 17 deg.
     MC = Magellanic Clouds; observations around the Small and Large Magellanic Clouds.
     S  = Survey Fields; scan observations of large, contiguous areas of the sky.
