The purpose of this page is to provide a quick overview of additional columns in the source catalogues which are published in DR1 (s. this page for downloads) and which are not generated by the eROSITA Science Analysis Software System (eSASS). Columns may also be missing compared to the catalogues generated by eSASS.
On this page
The catalogue is described in detail in this data model page
IAUNAME String containing the official IAU name of the source
SKYTILE Sky tile ID
UID Integer unique detection ID. It equals CatID×1011 +SKYTILE×105 +ID_SRC,
where CatID is 1 for the 1B detected Main and Supp catalogues and 2 for the 3B
detected Hard catalogue.
UID_Hard Hard catalogue UID of the source with a strong association, or -UID if the association
is weak. 0 means no counterpart found in the Hard catalogue. Only in the 1B
Main and Supp catalogues
UID_1B Main or Supp catalogue UID of the source with a strong association, or -UID if the
association is weak. 0 means no counterpart found in the 1B catalogues. Only in the
Hard catalogue
RA_RAW [deg] Right ascension (ICRS), corrected
DEC [deg] Declination (ICRS), corrected
POS_ERR [arcsec] 1-σ position uncertainty
ELON [deg] Ecliptic longitude
ELAT [deg] Ecliptic latitude
MJD Epoch of the observation of the source nearest to the optical axis of the telescope
MJD_MIN Epoch of the first observation of a source
MJD_MAX Epoch of the last observation of a source
FLAG_SP_SNR Source may lie within an overdense region near a supernova remnant
FLAG_SP_BPS Source may lie within an overdense region near a bright point source
FLAG_SP_SCL Source may lie within an overdense region near a stellar cluster
FLAG_SP_LGA Source may lie within an overdense region near a local large galaxy
FLAG_SP_GC_CONS Source may lie within an overdense region near a galaxy cluster
FLAG_NO_RADEC_ERR Source contained no RA_DEC_ERR in the pre-processed version of the catalogue
FLAG_NO_CTS_ERR Source contained no ML_CTS_0_ERR in the pre-processed version of the catalogue
FLAG_NO_EXT_ERR Source contained no EXT_ERR in the pre-processed version of the catalogue
FLAG_OPT Source might be affected by optical loading
