/* ** ** 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 58706.212688 0.000396 0.15429 0.03723 0.99270 0 2.23225 0.20243 1.90916 0.17313 0.34441 0.07701 0.29461 0.06588 58706.213568 0.000483 0.15189 0.03700 0.97006 0 1.90290 0.16822 1.61349 0.14261 0.28903 0.06561 0.24404 0.05540 58706.214442 0.000391 0.17742 0.04314 0.97037 0 2.03042 0.19380 1.72894 0.16500 0.36023 0.08056 0.30585 0.06839 58706.215345 0.000512 0.14738 0.03532 0.95480 0 1.87852 0.16203 1.60742 0.13865 0.27685 0.06191 0.23708 0.05301 58706.216192 0.000336 0.20292 0.04714 1.00000 0 2.26102 0.21838 1.93540 0.18693 0.45881 0.09694 0.39262 0.08295 58706.216872 0.000344 0.16776 0.04112 0.96639 0 2.39473 0.22139 2.04944 0.18946 0.40174 0.09120 0.34377 0.07804 58706.217524 0.000307 0.24049 0.06026 0.99057 0 1.85802 0.21011 1.58668 0.17942 0.44683 0.09991 0.38159 0.08533 58706.218166 0.000336 0.23874 0.06025 0.96552 0 1.73068 0.19082 1.47849 0.16301 0.41318 0.09380 0.35298 0.08013 58706.218967 0.000466 0.21380 0.04271 0.96894 0 2.15649 0.18057 1.84618 0.15458 0.46106 0.08362 0.39468 0.07158 58706.219746 0.000312 0.23501 0.05843 0.95370 0 1.93523 0.21039 1.65537 0.17996 0.45480 0.10170 0.38900 0.08698 58706.220429 0.000370 0.22043 0.04894 0.97699 0 2.12166 0.20448 1.81623 0.17505 0.46767 0.09353 0.40049 0.08010
