KVTTMCOMIS - Kvant TTM/COMIS X-Ray Source Catalog
A Catalog of X-ray sources as observed by the TTM/COMIS telescope onboard the Mir-Kvant observatory in 1988-1998. Emelyanov A.N., Aleksandrovich N.L., Sunyaev R.A. <Pis'ma Astron. Zh. 26, 355 (2000)> =2000PAZh...26..355E =2000AstL...26..297E
The name of the source. Most of the names are taken from the catalogs compiled by the Uhuru, Ariel-V and HEAO-1 observatories, and from the Einstein Catalog. Several sources were discovered by the TTM itself or by the Granat observatory. Their names in this catalog begin with KS (Kvant Source) or GRS (Granat Source), respectively.
The Right Ascension of the X-ray source in the selected equinox. This was given in J2000.0 coordinates to a precision of 0.1 seconds of time in the original table.
The Declination of the X-ray source in the selected equinox. This was given in J2000.0 coordinates to a precision of 0.1 arcminutes in the original table.
The Galactic Longitude of the X-ray source.
The Galactic Latitude of the X-ray source.
The date when the peak flux value of the X-ray source was measured.
The peak flux of the X-ray source in the 2-30 keV energy range recorded by TTM/COMIS, in units of 'milliCrabs'. Note that in this table the Crab Nebula is listed with a peak flux of 1239 mCrab. A typical conversion factor from mCrab to cgs is 1 mCrab = 2-3 x 10-11 erg s-1 cm-2.
The 1-sigma uncertainty in the peak flux of the TTM/COMIS X-ray source, in mCrab.
The total exposure time, in seconds, when the source was within the TTM field of view.
The total exposure time, in terms of the number of observing sessions or segments, when the source was within the TTM field of view.
The total time, in seconds, during which the source was detected by the TTM.
The total time, in terms of the number of observing sessions or segments, when the source was detected by the TTM.
The total time, in seconds, when the flux of the source was higher than 100 mCrab in the 2-30 keV energy band.
The total time, in terms of the number of observing sessions or segments, when the flux of the source was higher than 100 mCrab in the 2-30 keV energy band. In such sessions, information about the source spectrum can be obtained for individual sessions.
The ratio of the time during which the source Was visible to the total time it was within the TTM field of view.
The ratio of the time during which the source flux was higher than 100 mCrab to the total exposure time.
The number of observing sessions for each source during which it was identified by the TTM for which the efficiency of the Kvant High-Energy X-Ray Experiment (HEXE, energy range 15-200 keV) was nonzero.
Comments regarding the presumed nature of the source and its classification. The following abbreviations are used:
