This is a catalogue of some 250,000 well-confirmed infrared point sources observed by the Infrared Astronomical Satellite, i.e., sources with angular extents less than approximately 0.5, 0.5, 1.0, and 2.0 arcmin in the in-scan direction at 12, 25, 60, and 100 microns, respectively. http://irsa.ipac.caltech.edu/Missions/iras.html Catalog Research service-for ivo://wfau.roe.ac.uk/iras-dsa/ceaApplication iras_psc table: cone search of Point Source Catalog http://wfaudata.roe.ac.uk/iras-dsa/DirectCone?DSACAT=IRAS&DSATAB=iras_psc& 1.500000 2000000 false 32.5 60.0 0.5 Access to two applications: general ADQL query, and asynchronous cone-search where relevant/enabled. http://wfaudata.roe.ac.uk/iras-dsa/services/CommonExecutionConnectorService ivo://wfau.roe.ac.uk/iras-dsa/ceaApplication http://wfaudata.roe.ac.uk/iras-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/iras-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/iras-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/iras-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/iras-dsa/VOSI/tables GET application/xml http://wfaudata.roe.ac.uk/iras-dsa/VOSI/applications GET application/xml http://wfaudata.roe.ac.uk/iras-dsa/delegations GET application/xml Infrared iras_pscContains the parameters provided for each source in the IRAS PSC name Source Name ID_MAIN char seqNo sequential object number ID_NUMBER int cx unit vector of spherical co-ordinates POS_EQ_X double cy unit vector of spherical co-ordinates POS_EQ_Y double cz unit vector of spherical co-ordinates POS_EQ_Z double htmID Hierarchical Triangular Mesh (HTM) index, 20 deep, for equatorial co-ordinates POS_GENERAL long ra J2000 Celestial Right Ascension deg POS_EQ_RA_MAIN double dec J2000 Celestial Declination deg POS_EQ_DEC_MAIN double major Uncertainty ellipse major axis arcsec ERROR int minor Uncertainty ellipse minor axis arcsec ERROR int posAng Uncertainty ellipse position angle (East of North) deg POS_POS-ANG int nhcon Number of times observed (<25) NUMBER short flux_12 Averaged non-color corrected 12 micron flux density Jansky (1.0E-26 W/m**2/Hz) PHOT_FLUX_IR_12 double flux_25 Averaged non-color corrected 25 micron flux density Jansky (1.0E-26 W/m**2/Hz) PHOT_FLUX_IR_25 double flux_60 Averaged non-color corrected 60 micron flux density Jansky (1.0E-26 W/m**2/Hz) PHOT_FLUX_IR_60 double flux_100 Averaged non-color corrected 100 micron flux density Jansky (1.0E-26 W/m**2/Hz) PHOT_FLUX_IR_100 double fQual_12 12 micron flux density quality.
