/* ** ** 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 57579.733577 0.000582 0.19054 0.03070 0.97512 0 4.26386 0.27334 2.70852 0.16814 0.81244 0.12010 0.50577 0.07237 57579.734613 0.000454 0.25470 0.04100 0.97452 0 4.03316 0.29692 2.54691 0.18743 1.02723 0.14707 0.64792 0.09271 57579.735652 0.000584 0.18976 0.02932 0.98020 0 4.09416 0.25501 2.66438 0.16595 0.77689 0.10987 0.50589 0.07154 57579.736682 0.000446 0.26753 0.04281 0.97403 0 3.80795 0.27905 2.48016 0.18175 1.01873 0.14492 0.66433 0.09450 57579.737666 0.000538 0.19932 0.03077 0.96237 0 4.37865 0.27659 2.85308 0.18022 0.87273 0.12292 0.56789 0.07998 57579.738733 0.000530 0.22323 0.03500 0.96175 0 3.94712 0.26703 2.54871 0.17243 0.88111 0.12461 0.56913 0.08049 57579.739570 0.000307 0.16758 0.04054 0.95283 0 3.61237 0.33324 2.36929 0.21855 0.60536 0.13537 0.39670 0.08870 57579.740195 0.000318 0.15629 0.03820 0.99091 0 3.62624 0.32920 2.32037 0.21061 0.56676 0.12862 0.36284 0.08233 57579.740976 0.000463 0.24268 0.03870 0.96250 0 4.05199 0.28535 2.65161 0.18673 0.98334 0.14070 0.64371 0.09211 57579.741838 0.000399 0.13963 0.02875 0.98551 0 4.39651 0.32123 2.83955 0.20744 0.61391 0.11816 0.39772 0.07654 57579.742779 0.000541 0.19129 0.02992 0.95722 0 4.44496 0.28079 2.88272 0.18198 0.85026 0.12168 0.55381 0.07924 57579.744228 0.000909 0.21712 0.02587 0.96178 0 4.10362 0.21033 2.64689 0.13563 0.89097 0.09586 0.57541 0.06190
