/* ** ** 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 56386.824116 0.000394 0.34281 0.05649 0.97794 0 2.62944 0.21773 2.20649 0.18271 0.90140 0.12842 0.75662 0.10778 56386.824868 0.000359 0.36726 0.06159 0.99194 0 2.62792 0.22976 2.19511 0.19190 0.96512 0.13810 0.80601 0.11532 56386.825632 0.000405 0.35247 0.05848 0.98571 0 2.43537 0.21128 2.05939 0.17867 0.85841 0.12140 0.72584 0.10265 56386.826330 0.000292 0.45898 0.07914 1.00000 0 2.54420 0.24796 2.14966 0.20951 1.16773 0.16610 0.98666 0.14035 56386.827059 0.000437 0.37003 0.06142 0.96689 0 2.18891 0.18723 1.84273 0.15761 0.80996 0.11521 0.68256 0.09709 56386.828011 0.000515 0.36936 0.05097 0.99053 0 2.64623 0.19148 2.23732 0.16190 0.97741 0.11485 0.82653 0.09712
