/* ** ** 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 56830.998412 0.000312 0.40294 0.03432 1.00000 0 10.19206 0.46556 9.09224 0.41529 4.10675 0.29519 3.66377 0.26334 56830.999081 0.000350 0.36134 0.03056 0.98347 0 10.17687 0.43824 9.10878 0.39223 3.67728 0.26767 3.29371 0.23968 56830.999784 0.000353 0.36935 0.03062 0.99180 0 9.95171 0.42884 8.98212 0.38706 3.67566 0.26032 3.31756 0.23495 56831.000449 0.000312 0.39563 0.03368 0.99074 0 10.32968 0.46632 9.31737 0.42062 4.08674 0.29495 3.68637 0.26605 56831.001092 0.000330 0.37579 0.03149 1.00000 0 10.32448 0.45307 9.31233 0.40865 3.87982 0.27702 3.49943 0.24986 56831.001752 0.000330 0.37442 0.03185 1.00000 0 10.22808 0.45376 9.23015 0.40948 3.82955 0.27794 3.45575 0.25081 56831.002388 0.000307 0.40185 0.03415 1.00000 0 10.35991 0.47076 9.35406 0.42505 4.16312 0.29891 3.75895 0.26989 56831.003028 0.000333 0.34702 0.02877 1.00000 0 11.05706 0.46813 9.97775 0.42244 3.83701 0.27354 3.46241 0.24684 56831.003687 0.000327 0.40408 0.03412 1.00000 0 9.73247 0.44152 8.78055 0.39833 3.93270 0.28008 3.54813 0.25269 56831.004335 0.000321 0.41632 0.03543 1.00000 0 9.58479 0.44216 8.64880 0.39898 3.99033 0.28534 3.60084 0.25749 56831.004926 0.000269 0.44518 0.03844 0.97849 0 10.82749 0.51809 9.76718 0.46735 4.82018 0.34646 4.34821 0.31253 56831.005727 0.000532 0.34963 0.02375 0.98938 0 10.43001 0.35837 9.41158 0.32338 3.64663 0.21370 3.29067 0.19284
