/* ** ** Swift/XRT hardness ratio for 3C 273. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 57611.287263 0.000312 0.40226 0.06885 0.99074 0 2.68190 0.24795 2.29794 0.21245 1.07881 0.15539 0.92112 0.13267 57611.287891 0.000315 0.43728 0.07569 0.95413 0 2.52774 0.24258 2.15909 0.20719 1.10534 0.15921 0.94769 0.13650 57611.289257 0.001050 0.48374 0.04233 0.98072 0 2.68492 0.13436 2.29686 0.11493 1.29882 0.09325 1.11042 0.07972 57611.290984 0.000677 0.41025 0.04590 0.97863 0 2.81603 0.17126 2.42264 0.14733 1.15528 0.10849 0.99495 0.09343 57611.292269 0.000602 0.38763 0.04569 0.97596 0 3.00295 0.18684 2.56093 0.15932 1.16403 0.11652 0.99146 0.09925 57611.293212 0.000341 0.40580 0.06843 0.97458 0 2.54254 0.23351 2.14518 0.19699 1.03175 0.14593 0.87102 0.12318 57611.293863 0.000310 0.33924 0.05567 0.95327 0 3.36248 0.27491 2.88392 0.23578 1.14069 0.16230 0.97678 0.13898 57611.295249 0.001076 0.46133 0.03972 0.97312 0 2.79757 0.13527 2.38165 0.11515 1.29061 0.09195 1.09942 0.07833 57611.296679 0.000353 0.49877 0.07970 0.99180 0 2.31357 0.21576 1.98063 0.18470 1.15394 0.14973 0.98896 0.12832 57611.297732 0.000700 0.40277 0.04429 0.97107 0 2.88751 0.16853 2.46185 0.14368 1.16300 0.10837 0.99057 0.09229 57611.298725 0.000292 0.38709 0.06478 1.00000 0 3.03358 0.27136 2.56311 0.22926 1.17425 0.16607 0.99175 0.14025 57611.299352 0.000336 0.45254 0.07433 0.97414 0 2.54955 0.23552 2.16325 0.19981 1.15377 0.15670 0.97858 0.13292 57611.300053 0.000365 0.34783 0.05748 0.99206 0 2.69179 0.23016 2.30347 0.19695 0.93628 0.13242 0.80133 0.11333 57611.301578 0.001160 0.45808 0.03917 0.97756 0 2.65607 0.12719 2.25109 0.10778 1.21670 0.08621 1.03162 0.07310
