/* ** ** 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 59650.511885 0.001010 0.24915 0.02003 0.97994 0 8.16432 0.29504 4.63061 0.16712 2.03415 0.14605 1.16228 0.08332 59650.513792 0.000897 0.26985 0.02211 0.98710 0 8.37432 0.31784 4.75461 0.18041 2.25980 0.16412 1.28234 0.09308 59650.515621 0.000932 0.24091 0.01971 0.97516 0 9.08198 0.32461 5.12938 0.18331 2.18793 0.16101 1.23650 0.09095 59650.517447 0.000894 0.26532 0.02186 0.98382 0 8.51369 0.32366 4.84980 0.18437 2.25881 0.16514 1.28716 0.09411 59650.519249 0.000909 0.26563 0.02173 0.97771 0 8.59770 0.32210 4.84783 0.18159 2.28382 0.16609 1.28448 0.09335 59650.521179 0.001021 0.26234 0.01984 0.96884 0 9.00318 0.31020 5.07651 0.17485 2.36189 0.15900 1.32894 0.08944
