/* ** ** 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 56861.993969 0.000321 0.35050 0.02926 0.99099 0 11.14578 0.47413 10.27305 0.43704 3.90663 0.28062 3.60126 0.25865 56861.994603 0.000312 0.34401 0.02892 1.00000 0 11.51185 0.48842 10.57322 0.44855 3.96022 0.28741 3.64000 0.26418 56861.995251 0.000336 0.35504 0.02957 0.96552 0 10.84181 0.45711 10.02478 0.42266 3.84932 0.27648 3.55925 0.25565 56861.995908 0.000321 0.34817 0.02912 0.98198 0 11.24635 0.47499 10.39862 0.43919 3.91561 0.28270 3.62045 0.26139 56861.996547 0.000318 0.36590 0.03049 1.00000 0 10.82663 0.47362 9.95599 0.43552 3.96145 0.28090 3.64691 0.25857 56861.997184 0.000318 0.35048 0.02914 0.97273 0 11.42352 0.47814 10.56326 0.44213 4.00375 0.28756 3.70223 0.26590 56861.997829 0.000327 0.33960 0.02799 0.98230 0 11.46536 0.47459 10.60203 0.43886 3.89365 0.27749 3.60046 0.25660 56861.998503 0.000347 0.33151 0.02757 0.99167 0 10.88759 0.44915 10.06671 0.41529 3.60932 0.26059 3.33720 0.24094 56861.999406 0.000556 0.36026 0.02273 0.99479 0 11.12395 0.35951 10.21810 0.33025 4.00753 0.21713 3.68123 0.19943
