WISE Software Interface Specification; RvB_rex02; (WSDC D-I117) SIS Written by Howard McCallon, version 1.4, 02/12/2010 Interface Name: RvB (Reference-vs-Band file) Type of Interface: ASCII file in IPAC table format Read By: PRex/gnDSTR (Distortion Fitter) ..................... J.W. Fowler/ H.L. McCallon Written By: PRex/SFPRex (Single-Frame Position REconstruction) .. H.L. McCallon/ J.W. Fowler DESCRIPTION: One RvB file is generated for each band in the frameset. Each band file includes the band-frame positions of sources associated with 2MASS reference stars. The 2MASS star positions have been mapped into band-frame coordinates as well. When many of these files are used together they provide the data needed for gnDSTR to compute distortion coefficients. Additional information is provided by flags indicating which bands were used/rejected for b2r measurements in the SFPRex/FSFitR fit. These data could be useful at some future date to select a subset of the b2r measurements for gnDSTR use. RvB file formats of all four bands are identical, with descriptive text in the headers documenting each column variable. Note: The "co-sigma" of a pair of variables relates to the covariance as sqrt(abs(cov))*sign(cov) EXAMPLE: \ Reference-vs-Band (RvB) file for W1 (written by SFPRex ver 1.90 B00211 on 12-02-10 at 9:23:59) \ \ KEY WORDS: \BFXPIV = 508.5000000000 /X position of band-frame center pivot (pix) \BFYPIV = 508.5000000000 /Y position of band-frame center pivot (pix) \BFXSCALE= -0.000765386555 /X band-frame scale (deg/pix) \BFYSCALE= 0.000761500829 /Y band-frame scale (deg/pix) \ \ COLUMN HEADER DESCRIPTIONS: \ ig = merge group number assigned by SFPRex \ ib = band number \ ie = WISE extraction number \ xfd = Distorted X b-frame pos of WISE ext (pix) \ yfd = Distorted Y b-frame pos of WISE ext (pix) \ xfe = X b-frame pos of WISE ext w/dstr-cor (pix) \ yfe = Y b-frame pos of WISE ext w/dstr-cor (pix) \ sigxe = sigma X band-frame pos of WISE ext (pix) \ sigye = sigma Y band-frame pos of WISE ext (pix) \ sigxye = co-sigma XY band-frame pos of WISE ext (pix) \ xfr = pos of ref mapped to X band frame (pix) \ yfr = pos of ref mapped to Y band frame (pix) \ sigxr = X sig pos of ref mapped to band frame (pix) \ sigyr = Y sig pos of ref mapped to band frame (pix) \ sigxyr = XY co-sig of ref mapped to band frame (pix) \ 2MASS_ID = 2MASS reference ID \ b2rFLGS = ic=band#; N=>no mch, U=>mch used, R=mch rej \ dxf = xfe-xfr difference (pix) \ dyf = yfe-yfr difference (pix) \ dmag = WISE-Ref magnitude difference (mag) \ RAr = RA of reference star (deg) \ DECr = DEC of reference star (deg) \ frmID = Unique frame ID \ FT = Field Tag (CF=central;LL=lower-left;UL=upper-left;UR=upper-right;LR=lower-right \ |ig |ib|ie |xfd |yfd |xfe |yfe |sigxe |sigye |sigxye |xfr |yfr |sigxr |sigyr |sigxyr |2MASS_ID |b2rFLGS|dxf |dyf |dmag |RAr |DECr |frmID |FT| |i |i |i |r |r |r |r |r |r |r |r |r |r |r |r |c |c |r |r |r |r |r |c |c | | | | |pix |pix |pix |pix |pix |pix |pix |pix |pix |pix |pix |pix | | |pix |pix |mag |deg |deg | | | |null |nu|null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |nu| 4 1 4 467.2910 847.0400 466.5153 847.0702 0.6700 0.7260 0.0206 466.3622 847.1147 0.0218 0.0219 0.0000 01431066+6238365 UUUN 0.1531 -0.0446 0.0230 25.794424 62.643494 01622b224 CF 8 1 8 346.2630 106.4860 344.9827 106.5678 0.8500 0.7240 -0.0145 344.9650 106.5348 0.0218 0.0219 0.0000 01395007+6304094 UUUN 0.0177 0.0330 -0.0800 24.958656 63.069283 01622b224 CF 34 1 34 347.6640 81.8580 346.2090 81.9754 0.8360 0.8520 0.0185 346.2655 82.0845 0.0218 0.0255 -0.0000 01394516+6305076 UUUU -0.0565 -0.1091 -0.6410 24.938185 63.085461 01622b224 CF 44 1 44 997.5740 374.1330 997.7935 374.3338 0.7920 0.7800 -0.0154 997.6818 374.1911 0.0218 0.0219 0.0000 01443198+6309515 UUUN 0.1116 0.1427 -0.1170 26.133268 63.164310 01622b224 CF 46 1 46 29.3630 688.3550 28.2073 688.6864 1.0260 0.7280 0.0131 28.1936 688.8122 0.0218 0.0219 0.0000 01400931+6233549 UUUN 0.0137 -0.1258 -0.0360 25.038817 62.565254 01622b224 UL
