/* ** ** 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 55319.536638 0.000865 0.27843 0.02243 0.98997 0 5.54625 0.20910 4.84508 0.18264 1.54427 0.10991 1.34679 0.09584 55319.538377 0.000874 0.28195 0.02292 0.96026 0 5.47739 0.20614 4.82649 0.18164 1.54433 0.11129 1.36076 0.09806 55319.540171 0.000920 0.25586 0.02039 0.96541 0 5.75718 0.20635 5.07487 0.18190 1.47304 0.10482 1.29854 0.09240 55319.541989 0.000897 0.25178 0.02023 0.97419 0 5.90559 0.21253 5.20297 0.18725 1.48693 0.10682 1.31002 0.09411 55319.543748 0.000862 0.24434 0.01962 0.98322 0 6.25547 0.22132 5.51211 0.19502 1.52846 0.11015 1.34682 0.09706 55319.545577 0.000966 0.23491 0.01877 0.97605 0 5.84691 0.20185 5.15278 0.17789 1.37351 0.09898 1.21049 0.08724 55319.547443 0.000900 0.25811 0.02049 0.97749 0 5.80724 0.20884 5.11896 0.18408 1.49893 0.10606 1.32126 0.09349 55319.549520 0.001178 0.22001 0.01646 0.97543 0 5.79086 0.18286 5.10287 0.16114 1.27402 0.08643 1.12266 0.07616
