1 PSC PSC (Point Source Catalog) This is a general utility to look through the compacted IRAS Point Source Catalog. This program is able to select sources according to various criteria and to create binary tables and/or formatted files containing the information about the sources. Even on tape, the program is fast to select sources (less than 8 minutes in any small positional box, and often less). The time needed to list the information may be longer if you select many sources.. It requests as input a compacted file containing the full catalog information and a table containing pointers to this compacted file, as well as positional and flux information. The compacted catalog can be either on magnetic tape (GAG242 at the Groupe d'Astrophysique in Grenoble), or on disk (with logical name PSC_COMPACT). The input table must be on disk. It can be either the default table IRAS_PSC_EQU (full catalog) or any previous output of the program (to work on a reduced source list). The task produces as output a formatted file and/or an output table. A description of the formatted output can be obtained in GRAPHIC or OVERLAY by HELP PSC_IRAS FORMAT. Reference to the IRAS explanatory supplement will probably be needed except for IRAS wizards. The output table has the same content as the input one (but of course only for selected sources) and can therefore be used as input to another run of the program: as an example, this will allow to select first on the 12/25 color and then on the 60/100 color. Since this table is a standard GreG table, it can also be used in GreG's COLUMN command to produce plots. Column 1 is Right Ascension (in radians), column 2 is Declination (also in radians). Columns 3 to 6 contain the 4 fluxes (12 to 100), with upper limits coded as negative. Column 7 is an internal pointer. This can be used for example, to plot the distribution on the sky of a given class of sources. After some simple processing (in SIC), color/color plots can easily be produced. 2 IN_TABLE$ TASK\FILE "Input table" IN_TABLE$ The name of the input table. Answer * if you want to search through the whole catalog. If you want to search through a subset of the catalog (obtained from a previous run of the program), specify the name of the corresponding table. 2 F_OUT$ TASK\LOGICAL "Create a formatted output" L_OUT$ Answer YES if you want to create a formatted output, NO otherwise. Don't answer YES if you expect to select half of the catalog! 2 OUT_LIST$ TASK\FILE "Formatted output file name" OUT_LIST$ The name of the formatted output file. This is only used if you create one. 2 T_OUT$ TASK\LOGICAL "Create an output table" T_OUT$ Answer YES if you want to create an output table, otherwise answer NO. The output table can be used as input for another run of the program if you want to work on a subset of the catalog. It can also be used in GreG to produce things like color/color plots. See the main help for a description of its content. 2 OUT_TABLE$ TASK\FILE "Output table name" OUT_TABLE$ The name of the output table. This is only used if you create one. 2 CHECK_BOX$ TASK\LOGICAL "Select on coordinates" CHECK_BOX$ Answer YES if you want to select on Right Ascension and Declination, NO otherwise. Selection on LII and BII may be implemented one day. Ask T. Forveille if you need it. 2 BOX$ TASK\REAL "Box limits (RAmin,RAmax,DECmin,DECmax)" BOX$[4] These are the limits of the search box: RAmin, RAmax, DECmin, DECmax. At present, these should be entered in radians. This will hopefully be replaced by a more convenient format one day. Remind T. Forveille that this has to be done. 2 CHECK_QUAL$ TASK\LOGICAL "Select on flux quality" CHECK_QUAL$ Answer YES if you want to select on flux qualities, NO otherwise. 2 QUALITY$ TASK\INTEGER "Desired flux qualities" QUALITY$[4] The minimal flux quality you are willing to accept in each band (12, 25, 60, and 100 microns). 3 is good, 2 poor, 1 an upper limit. 2 CHECK_ID$ TASK\LOGICAL "Select on identifications" CHECK_ID$ Answer YES if you want to select on the identification type, NO otherwise. 2 WANTED_ID$ TASK\INTEGER "Enter identifications" WANTED_ID$ Enter the accepted identification types. Possible values of the identification type are: - 1: association with an extragalactic catalog. - 2: association with a stellar catalog. - 3: association with other catalogs (planetary nebulae, HII regions, reflection nebulae...). - 4: association with several of the previous types of catalogs (stellar+ extragalactic for example). 2 CHECK_CATA$ TASK\LOGICAL "Select on catalog number" CHECK_CATA$ Answer YES if you want to select sources in one particular association catalog (IRC, or Zwicky, or de Vaucouleurs, or...), NO otherwise. 2 WANTED_CATA$ TASK\INTEGER "Catalog number" WANTED_CATA$ This is a code for the association catalog. The meaning of the code is the following: - 1 General Catalog of Variable Stars - 2 Dearborn (Faint Red Stars) - 3 AFGL (=CRL, =AFCRL) Revised - 4 IRC 2 Micron Sky Survey - 5 Wesselius Globules (unpublished) - 6 Second reference catalog, De Vaucouleurs (Bright Galaxies) - 7 Emission Lines Stars - 8 Equatorial Infrared Catalog - 9 UPPSALA Galaxy Catalog - 10 Morphological Catalog of Galaxies - 11 Planetary Nebula Strasbourg - 12 Zwicky (Galaxies and Clusters) - 13 SAO - 14 ESO/UPPSALA Galaxy Catalog - 15 Bright Stars (HR) - 16 Suspected Variable Stars - 17 Cool Carbon Stars - 18 Gliese (Nearby Stars) - 19 S Stars - 20 Parkes HII regions - 21 Bonn HII regions - 22 Blitz (CO velocity in HII regions) - 23 Lynds and others... (Nebulosities) - 24 IRC with good positions - 25 Dwarf Galaxies - 26 Peculiar Galaxies (Arp) - 27 Markarian (Galaxies with UV) - 28 Strong 5 GHz (> 1 Jy, Kuhr) - 29 Veron-Veron (Quasars and Active Nuclei) - 30 Zwicky (Galaxies) - 31 Interacting Galaxies (Vorontsov and Velyaminov.) 2 CHECK_RATIO$ TASK\LOGICAL "Select on flux ratios" CHECK_RATIO$ Answer YES if you want to select on the ratio of two fluxes, NO otherwise. 2 BAND$ TASK\INTEGER "Bands for flux ratio" BANDS$[2] The names of the two band used in the ratio. For example 25 and 60 if you want to select on the ration 25/60. 2 MIN_RATIO$ TASK\REAL "Minimum flux ratio" MIN_RATIO$ The minimum value of the ratio you are willing to accept. 2 MAX_RATIO$ TASK\REAL "Maximum flux ratio" MAXRATIO$ ! The maximum value of the ratio you are willing to accept. 2 CHECK_LUM$ TASK\LOGICAL "Select on total flux" CHECK_LUM$ Answer YES if you want to select on the integrated IRAS flux, NO otherwise. 2 MIN_LUM$ TASK\REAL "Minimum total flux" MIN_LUM$ The minimum integrated flux you are willing to accept. The unit for integrated flux is one solar luminosity at one kiloparsec. 2 CHECK_FLUX$ TASK\LOGICAL "Select on one flux" CHECK_FLUX$ Answer YES if you want to select on a minimum flux in one band, NO otherwise. 2 MIN_BAND$ TASK\INTEGER "Band for minimum flux" MIN_BAND$ The name of the band on which you want to select. 2 MIN_FLUX$ TASK\REAL "Minimum flux in band" MIN_FLUX$ The minimum flux in band MIN_BAND$ you are willing to accept. The unit is one Jansky. 2 CHECK_LRS$ TASK\LOGICAL "Select on LRS spectral type" CHECK_LRS$ Answer YES if you want to select on the Low Resolution Spectrometer spectral type, NO otherwise. 2 LRS_TYPE$ TASK\CHARACTER "LRS type and subtype" LRS_TYPE$ The LRS spectral type you want to select. Refer to the Explanatory Suplement for a description of the spectral types. Specify 5* if you want to select all sources with spectral type 5 (for example), and 51 if you want to select only the sources with spectral type 5 and subtype 1. 2 TAPE$ TASK\CHARACTER "Input tape drive for full catalog" TAPE$ The name of the tape drive on which you will mount the full catalog. This information will only be used if the catalog is not on disk and the selection criteria that you specified need the full catalog. Otherwise, you must nonetheless answer something, but anything will do. 1 END
