/* ** ** Swift/XRT hardness ratio for Mrk 501. ** 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 59326.121583 0.000796 0.28058 0.02287 0.96000 0 6.11096 0.23202 5.31161 0.20168 1.71460 0.12370 1.49387 0.10776 59326.123151 0.000773 0.26304 0.02171 0.99251 0 6.41489 0.23947 5.57099 0.20797 1.68734 0.12419 1.46452 0.10778 59326.124815 0.000891 0.29009 0.02271 0.98281 0 5.73036 0.21187 4.97498 0.18394 1.66232 0.11468 1.44123 0.09943 59326.168163 0.000883 0.24855 0.01980 0.97049 0 6.08021 0.21604 5.41099 0.19224 1.51121 0.10778 1.34439 0.09586 59326.169945 0.000900 0.24208 0.01921 0.96785 0 6.10340 0.21235 5.45969 0.18995 1.47750 0.10535 1.32206 0.09427 59326.172211 0.001366 0.27919 0.01783 0.98093 0 5.59558 0.16567 5.00189 0.14809 1.56220 0.08838 1.39646 0.07899
