/* ** ** 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 59044.043553 0.000587 0.21583 0.03439 0.98030 0 2.92894 0.19471 2.28157 0.15166 0.63214 0.09154 0.49286 0.07138 59044.044719 0.000573 0.25141 0.04002 0.95455 0 2.74726 0.19601 2.09322 0.14935 0.69069 0.09827 0.52722 0.07500 59044.045767 0.000475 0.25857 0.04168 0.98171 0 3.14725 0.23351 2.38401 0.17685 0.81379 0.11647 0.61567 0.08811 59044.046745 0.000503 0.30985 0.05067 0.98276 0 2.48718 0.19958 1.90578 0.15291 0.77066 0.10982 0.58833 0.08383 59044.047699 0.000451 0.27759 0.04490 0.96154 0 3.18557 0.24011 2.38642 0.17987 0.88428 0.12654 0.66082 0.09457 59044.048750 0.000599 0.21963 0.03454 0.98068 0 2.93874 0.19706 2.23638 0.14995 0.64542 0.09182 0.49086 0.06983 59044.049878 0.000530 0.24053 0.03865 0.97814 0 3.01140 0.21510 2.28809 0.16343 0.72432 0.10427 0.55085 0.07930 59044.050859 0.000451 0.25913 0.04179 0.96795 0 3.33363 0.24775 2.53194 0.18819 0.86384 0.12364 0.65645 0.09394 59044.051768 0.000457 0.25930 0.04131 0.98101 0 3.28457 0.24074 2.49620 0.18295 0.85168 0.12046 0.64624 0.09139 59044.052792 0.000567 0.22378 0.03520 0.96939 0 3.09469 0.21313 2.35752 0.16235 0.69254 0.09795 0.52719 0.07456 59044.054438 0.001079 0.23743 0.02731 0.97855 0 2.88859 0.14776 2.20268 0.11268 0.68583 0.07065 0.52262 0.05383
