WISE Software Interface Specification; BBpS_rex18; (WSDC D-I199) SIS Written by Howard McCallon, version 1.0, 08/02/2013 Interface Name: BBps (Band-to-Band plus Scales file) Type of Interface: ASCII file in IPAC table format Read By: PRex/MFPRex (Multi-Frame Position REconstruction) ... H.L. McCallon/ J.W. Fowler Written By: Off-line code/scripts ............................... H.L. McCallon DESCRIPTION: The BBpS files provide a time history band-to-band differences and per band scale change changes over the entire mission. The values contained therein were derived from the SFPRex QA fits which were generated but not used for AllSky. There are a total of 12 BBpS files separated by band and further broken down into three subsets by scan direction (ASC, DES & ALL). The "ASC" values were generated using only ascending data, the "DES" values using only descending data and the "ALL" values were generated combining ascending and descending. Each file name encodes the band number, scan direction tag, as well as a file version code number. wise-w1-bbps-all-B30124.tbl wise-w1-bbps-asc-B30124.tbl wise-w1-bbps-des-B30124.tbl wise-w2-bbps-all-B30124.tbl wise-w2-bbps-asc-B30124.tbl wise-w2-bbps-des-B30124.tbl wise-w3-bbps-all-B30124.tbl wise-w3-bbps-asc-B30124.tbl wise-w3-bbps-des-B30124.tbl wise-w4-bbps-all-B30124.tbl wise-w4-bbps-asc-B30124.tbl wise-w4-bbps-des-B30124.tbl \ \ COLUMN HEADER DESCRIPTIONS: \ WinTag = Time window tag \ JDc = Central Julian date of gnDSTR fit window (day) \ JD0 = Start Julian date of use window (day) \ JDf = End Julian date of use window (day) \ dXf_bar = Mean dXf band difference w.r.t. w1 (asec) \ dXf_sig = Sigma (pop) dXf band difference w.r.t. w1 (asec) \ dYf_bar = Mean dYf band difference w.r.t. w1 (asec) \ dYf_sig = Sigma (pop) dYf band difference w.r.t. w1 (asec) \ dTf_bar = Mean rotation difference w.r.t. w1 (asec) \ dTf_sig = Sigma (pop) rotation difference w.r.t. w1 (asec) \ dsx_bar = Mean fractional Xf scale difference w.r.t. apriori \ dsx_sig = Sigma (pop) of fractional XF scale difference w.r.t. apriori \ dsy_bar = Mean fractional Yf scale difference w.r.t. apriori \ dsy_sig = Sigma (pop) of fractional YF scale difference w.r.t. apriori \ nmch = number of measurements used for time window \ MisPhase = Mission phase of time window (4b-cryo, 3b-cryo or PostCryo) The number of time windows varies with band (w1=196, w2=186, w3=87, w4=69). The BBpS window counts in each band are tied to the gnDSTR fit windows, which in turn were selected based on a tradeoff between available source counts and variability with time. The JDc values, due to discontinuity aviodance during gnDSTR fit window selection, are not necessarily the average of the JD0 and JDf values. The JDc values are included for information only and are not need to make use of the BBpS data. Note that since the dXf, dYf and dTf values are w.r.t. w1 they have no meaning for the w1 BBpS files so those columns have been dropped from the w1 BBpS files. EXAMPLE: As an example the first few lines of the w2 ASC BBpS file are shown: | WinTag| JDc | JD0 | JDf |dXf_bar|dXf_sig|dYf_bar|dYf_sig|dTf_bar |dTf_sig| dsx_bar | dsx_sig | dsy_bar | dsy_sig |nmch |MisPhase| | c | r | r | r | r | r | r | r | r | r | r | r | r | r | i | char | | | day | day | day | asec | asec | asec | asec | asec | asec | | | | | | | | null | null | null | null | null | null | null | null | null | null | null | null | null | null | null| null | WIN001 205.42750000 2455203.57000000 2455207.28500000 0.3008 0.0188 1.9768 0.0191 877.7848 8.4134 5.12780E-06 7.08240E-05 -1.13371E-05 4.85738E-05 7965 4b-cryo WIN002 209.14250000 2455207.28500000 2455211.00000000 0.3009 0.0184 1.9760 0.0191 877.6765 8.3454 3.35487E-06 7.03316E-05 -9.23530E-06 4.71610E-05 7875 4b-cryo WIN003 212.54375000 2455211.00000000 2455214.08750000 0.3036 0.0178 1.9750 0.0182 884.7336 8.1273 -7.89189E-06 6.85276E-05 -3.80851E-06 4.46334E-05 10348 4b-cryo WIN004 215.63125000 2455214.08750000 2455217.17500000 0.3036 0.0179 1.9749 0.0184 885.2379 8.7291 -1.58458E-05 6.93439E-05 -3.28718E-06 4.47927E-05 10119 4b-cryo WIN005 218.71875000 2455217.17500000 2455220.26250000 0.3035 0.0171 1.9746 0.0181 885.7263 8.2973 -1.99564E-05 6.71696E-05 -2.30809E-06 4.52290E-05 10243 4b-cryo WIN006 221.80625000 2455220.26250000 2455223.35000000 0.3033 0.0180 1.9756 0.0186 885.5782 9.0273 -1.79384E-05 7.37219E-05 -2.64417E-06 4.59913E-05 9702 4b-cryo
