/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 58133.403960 0.000275 0.32974 0.01215 1.00000 0 68.08864 1.25004 63.56976 1.16707 22.45164 0.71690 20.96438 0.66941 58133.404504 0.000269 0.34309 0.01284 1.00000 0 67.02188 1.26819 62.18417 1.17659 22.99433 0.74220 21.33325 0.68842 58133.405051 0.000278 0.34596 0.01288 1.00000 0 64.54412 1.21804 60.21682 1.13638 22.32968 0.71625 20.83263 0.66823 58133.405589 0.000260 0.36748 0.01378 1.00000 0 64.74813 1.26244 60.40622 1.17778 23.79381 0.76218 22.19825 0.71107 58133.406107 0.000258 0.36244 0.01350 1.00000 0 66.72002 1.28048 62.24483 1.19459 24.18170 0.77191 22.55973 0.72013 58133.406631 0.000266 0.34417 0.01280 1.00000 0 67.42687 1.27031 62.90583 1.18514 23.20639 0.74451 21.65035 0.69459 58133.407169 0.000272 0.34993 0.01296 1.00000 0 65.35731 1.23932 60.97374 1.15620 22.87057 0.72769 21.33659 0.67888 58133.407704 0.000263 0.35694 0.01326 1.00000 0 65.98252 1.26606 61.55934 1.18119 23.55182 0.74909 21.97300 0.69887 58133.408242 0.000275 0.34376 0.01280 1.00000 0 65.30737 1.23745 60.92780 1.15446 22.45022 0.71927 20.94466 0.67103 58133.408778 0.000260 0.35217 0.01321 1.00000 0 66.81911 1.27943 62.33911 1.19365 23.53160 0.75879 21.95388 0.70792 58133.409365 0.000327 0.37491 0.01243 0.99637 0 64.87212 1.12669 60.52289 1.05116 24.32117 0.68673 22.69063 0.64069
