... rgsregions defines and constructs the various RGS event-selection regions, and adds them to the source list (see rgssources ). ... Image regions and the background region refer to the plane of dispersion versus cross-dispersion ( image plane ) and select events based on their spatial coordinates. ... The order regions refer to the plane of dispersion versus calibrated pulse-height ( energy plane ) and select events from a specific astrophysical source within a particular reflection order. ...

... Acero+ astro-ph/1501.02003v1.pdf Fermi Large Area Telescope Third Source Catalog Acero+, 2015) Version by Trushkin from FITS file with five columns =========================================================================== We present the third Fermi Large Area Telescope source catalog (3FGL) of sources in the 100 MeV-300 GeV range. ... From source counts of Galactic sources we estimate the contribution of unresolved sources to the Galactic diffuse emission is 3% at 1 GeV. ...

Optical identifications of subsample of steep spectra radio sources from RC catalog using 6m SAO telescope of SAO RAS: optical observations. ... Astronomy Reports. ... Identification of radio sources with data of various radio catalogs allows one to construct continual spectrum of the object and its radio structure. ...

... The actual cross-correlations were done as follows: north of WGACAT was correlated with the GB6 catalog with a correlation radius of one arc minute. ... We therefore cross-correlated WGACAT with the GB6 and PMN radio catalogs with a 1.5 arcmin radius. ... As a result of this experiment, we then added to the WGACAT/PMN candidate list the 29 unclassified sources obtained from the 1.5 arcmin correlation and having PSPC offsets arcmin, ratio between X-ray/radio offset and positional error , and . ...
