/* ** ** 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 57840.184131 0.000593 0.16160 0.01243 0.99024 0 13.27353 0.37995 12.24809 0.35060 2.14503 0.15312 1.97931 0.14129 57840.185303 0.000579 0.15529 0.01238 0.97500 0 13.89280 0.39525 12.74445 0.36253 2.15741 0.16069 1.97969 0.14743 57840.186613 0.000732 0.12474 0.00948 0.97628 0 14.02491 0.35131 12.91008 0.32339 1.74948 0.12552 1.61050 0.11555 57840.187979 0.000634 0.13865 0.01059 1.00000 0 14.22307 0.38036 13.08964 0.35003 1.97209 0.14105 1.81469 0.12979 57840.189186 0.000573 0.16120 0.01263 0.98990 0 13.62570 0.39429 12.42256 0.35947 2.19652 0.15987 2.00276 0.14573 57840.190358 0.000599 0.15961 0.01229 0.98068 0 13.42806 0.38116 12.33689 0.35017 2.14323 0.15340 1.96945 0.14094 57840.191605 0.000648 0.14176 0.01097 0.97768 0 13.85073 0.37204 12.69903 0.34108 1.96348 0.14251 1.80157 0.13075 57840.192817 0.000564 0.16256 0.01266 0.98974 0 13.78852 0.39853 12.57394 0.36337 2.24144 0.16215 2.04231 0.14776 57840.193977 0.000596 0.15409 0.01178 0.99515 0 13.89414 0.38922 12.64009 0.35405 2.14095 0.15225 1.94654 0.13843 57840.195181 0.000608 0.14441 0.01123 0.99524 0 14.23740 0.39113 13.02014 0.35764 2.05601 0.14961 1.87818 0.13667
