/* ** ** 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 55982.141723 0.000616 0.16251 0.01250 0.99531 0 12.72908 0.36459 11.58057 0.33168 2.06863 0.14768 1.88351 0.13444 55982.142927 0.000587 0.17318 0.01372 0.99015 0 12.57235 0.37826 11.22537 0.33774 2.17723 0.15953 1.94312 0.14244 55982.144145 0.000631 0.16021 0.01234 0.98165 0 12.94259 0.36867 11.58976 0.33011 2.07349 0.14840 1.85654 0.13286 55982.146005 0.001230 0.15098 0.00852 0.99044 0 13.07786 0.26510 11.72389 0.23764 1.97447 0.10404 1.77176 0.09334 55982.209339 0.000828 0.13957 0.01086 0.97552 0 13.06883 0.35332 10.02309 0.27059 1.82396 0.13313 1.40522 0.10248 55982.211125 0.000958 0.12136 0.00939 0.98792 0 13.01898 0.32633 9.87151 0.24743 1.58004 0.11563 1.19981 0.08781 55982.212953 0.000871 0.14309 0.01098 0.98671 0 12.45256 0.33684 9.35783 0.25310 1.78184 0.12801 1.33840 0.09616 55982.214640 0.000816 0.14201 0.01074 0.99291 0 13.28549 0.35748 10.07233 0.27099 1.88667 0.13342 1.43095 0.10118 55982.216405 0.000949 0.12848 0.00954 0.99085 0 13.22252 0.33161 10.04783 0.25199 1.69885 0.11873 1.29089 0.09022
