-xd-mcat.fits: -tab Jan'05 May'06 Oct '07 Binary FITS table column descriptions for *-xd-mcat.fits files: (Total number of fields: 337.) General comments: Uppercase column names originate from the source extractor program (SExtractor) which operates on each band separately. These values are copied verbatim from the source extractor result files (*-n/fd-cat.fits) and have either an NUV_ or FUV_ prepended to the column name. For these columns, -99.0 is used for unfilled (or blank) values, but in some cases blank magnitude values appear as +99.0. Lowercase column names are added by the band merger program. For these columns, -999.0 or -9999.0 are unfilled or blank values. Magnitudes are either AB or GALEX as stated. Fluxes are counts/second unless stated to be in micro Janskys. ggoid_hex : TTYPE1 (16A) : 'string ' : Hex string of Galex Global Object ID This is a hexidecimal string version of the global object ID. ggoid_dec : TTYPE2 (20A) : 'string ' : Decimal string of Galex Global Object ID This is a decimal string version of the global object ID. ggoid : TTYPE3 (2J) : 'number ' : Galex Global Object ID This is the 64-bit integer version of the global object ID. Joining these two integers yields a 64 bit integer uniquely identifying this source including the tile number, band, product number, reduction try (path), etc. These values are also given as individual columns (shown below).

Currently, the radial positional error is set at a constant 1.0 arcsecond for all sources. (NOTE: In data products of April 2006 and earlier, i.e. GR1 and GR2, this value was computed with wrong degrees of freedom (nu=1 instead of nu=2) and so may not be useful.) sep : TTYPE20 (1E) : 'arcseconds' : Separation between band positions. Separation between two bandmerged (NUV and FUV) source positions in arcseconds. E_bv : TTYPE21 (1E) : 'number ' : E(B-V) Galactic Reddening.

Since the telescope is dithered and many eclipse observations are combined, this is only an estimate of the X position. The units are in pixels (1.5 arcseconds per pixel) relative to the nominal field center. nuv_det_y : TTYPE27 (1E) : 'value ' : NUV detector Y position Estimate of NUV detector Y position of a given source in pixels (1.5 arcseconds per pixel). fuv_det_x : TTYPE28 (1E) : 'value ' : FUV detector X position Estimate of FUV detector X position of a given source in pixels (1.5 arcseconds per pixel). fuv_det_y : TTYPE29 (1E) : 'value ' : FUV detector Y position Estimate of FUV detector Y position of a given source in pixels (1.5 arcseconds per pixel). chkobj_type : TTYPE30 (1J) : 'number ' : Astrometry check type The GALEX field position is aligned to the sky using the known positions of bright stars.

If the value of "chkobj_type" for a source is 1, then that source (NUV position) has been matched to a known bright star. chkobj_id : TTYPE31 (1J) : 'number ' : Astrometry check ID For a source matched to a known star (chkobj_type=1), this column gives the row number in the match table file (-cat_mch_rtastar.fits) containing the data for this match. chkobj_r : TTYPE32 (1E) : 'degrees ' : Astrometry check radius in degrees For a source matched to a known star (chkobj_type=1), this column gives the distance in degrees between the known star and the GALEX NUV source position. chkobj_pa : TTYPE33 (1E) : 'degrees ' : Astrometry check position angle in degrees For a source matched to a known star (chkobj_type=1), this column gives the position angle in degrees between the known star position and the GALEX NUV source position. misc_flags : TTYPE34 (1J) : 'value ' : Miscellaneous flags Not used. nuv_flux : TTYPE35 (1E) : 'flux ' : NUV calibrated flux (micro Jansky) NUV flux derived from a NUV source catalog flux. The FITS header card "CALMAG" indicates which NUV flux value is used, e.g. if CALMAG=AUTO, then the NUV_FLUX_AUTO column is used. The NUV catalog flux is in counts per second, this is converted to micro Janskys using the header card "N_CUJ": nuv_flux = NUV_FLUX_AUTO * N_CUJ. The value of "N_CUJ" is equal to 10 ^ ( (NUV_ZPMAG - 23.9) / -2.5 ) . Also note that "nuv_flux" may be zero, in this case refer to the "NUV_FLUX_*" columns for flux values. If "nuv_flux" has a value of -999, then there was no NUV source detection. (See "nuv_mag" for 0.2% error notice.) nuv_fluxerr : TTYPE36 (1E) : 'flux ' : NUV calibrated flux error (micro Jansky) Error for nuv_flux value. nuv_mag : TTYPE37 (1E) : 'mag ' : NUV calibrated AB magnitude NUV magnitude derived from a NUV source catalog magnitude. The FITS header card "CALMAG" indicates which NUV magnitude value is used, e.g. if CALMAG=AUTO, then the NUV_MAG_AUTO column is used. The NUV catalog magnitude is converted to the true magnitude using the zero-point conversion (see header card "N_ZPMAG": nuv_mag = NUV_MAG_AUTO + N_ZPMAG). NOTE: The flat field was calibrated using N_ZPMAG = 20.08 rather than 20.08238, this means that there is 0.2% error in the values of "nuv_mag" for all data released until at least the end of 2006. nuv_magerr : TTYPE38 (1E) : 'mag ' : NUV calibrated AB magnitude error Error for nuv_mag value. fuv_flux : TTYPE39 (1E) : 'flux ' : FUV calibrated flux (micro Jansky) FUV flux derived from a FUV source catalog flux. The FITS header card "CALMAG" indicates which FUV flux value is used, e.g. if CALMAG=AUTO, then the FUV_FLUX_AUTO column is used. The FUV catalog flux is in counts per second, this is converted to micro Janskys using the header card "F_CUJ": fuv_flux = FUV_FLUX_AUTO * F_CUJ. The value of "F_CUJ" is equal to 10 ^ ( (FUV_ZPMAG - 23.9) / -2.5 ) . Also note that "fuv_flux" may be zero, in this case refer to the "FUV_FLUX_*" columns for flux values. If "fuv_flux" has a value of -999, then there was no FUV source detection. (See "fuv_mag" for 0.3% error notice.) fuv_fluxerr : TTYPE40 (1E) : 'flux ' : FUV calibrated flux error (micro Jansky) Error for fuv_flux value. fuv_mag : TTYPE41 (1E) : 'mag ' : FUV calibrated AB magnitude FUV magnitude derived from a FUV source catalog magnitude. The FITS header card "CALMAG" indicates which FUV magnitude value is used, e.g. if CALMAG=AUTO, then the FUV_MAG_AUTO column is used. The FUV catalog magnitude is converted to the true magnitude using the zero-point conversion (see header card "F_ZPMAG": fuv_mag = FUV_MAG_AUTO + F_ZPMAG). NOTE: The flat field was calibrated using F_ZPMAG = 18.82 rather than 18.81707, this means that there is 0.3% error in the values of "fuv_mag" for all data released until at least the end of 2006. fuv_magerr : TTYPE42 (1E) : 'mag ' : FUV calibrated AB magnitude error Error for fuv_mag value. nuv_s2n : TTYPE43 (1E) : 'ratio ' : NUV signal-to-noise from 'AUTO' flux value This is the ratio of NUV_FLUX_AUTO and NUV_FLUXERR_AUTO. fuv_s2n : TTYPE44 (1E) : 'ratio ' : FUV signal-to-noise from 'AUTO' flux value This is the ratio of FUV_FLUX_AUTO and FUV_FLUXERR_AUTO. nuv_fcat_flux : TTYPE45 (1E) : 'flux ' : NUV calibrated flux (micro Jansky) using FUV catalog position The NUV flux derived using the source position given in the FUV catalog.
