/* ** ** 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 58365.355417 0.000370 0.24076 0.06017 0.97656 0 1.54860 0.17286 1.33179 0.14865 0.37284 0.08337 0.32053 0.07167 58365.356143 0.000356 0.23820 0.05970 0.99187 0 1.63193 0.18469 1.38322 0.15651 0.38873 0.08693 0.32842 0.07344 58365.356893 0.000394 0.21351 0.05353 0.96324 0 1.67256 0.17860 1.41215 0.15078 0.35711 0.08100 0.30209 0.06849 58365.357749 0.000463 0.18461 0.04515 0.95625 0 1.68777 0.16714 1.41300 0.13994 0.31158 0.06968 0.26187 0.05856 58365.358632 0.000420 0.19056 0.04800 0.97931 0 1.70326 0.17503 1.44304 0.14827 0.32458 0.07465 0.27521 0.06328 58365.359506 0.000454 0.17641 0.04352 0.96178 0 1.76226 0.17141 1.48554 0.14448 0.31088 0.07047 0.26208 0.05942 58365.360605 0.000645 0.11450 0.02712 0.97309 0 1.90551 0.14850 1.60949 0.12542 0.21818 0.04879 0.18464 0.04129 58365.361783 0.000532 0.15806 0.03802 0.95109 0 1.69211 0.15005 1.44684 0.12830 0.26746 0.05981 0.22895 0.05120 58365.362772 0.000457 0.17722 0.04313 0.96835 0 1.76083 0.16916 1.48038 0.14222 0.31206 0.06978 0.26187 0.05856 58365.363765 0.000535 0.16594 0.04013 0.97297 0 1.58764 0.14616 1.34247 0.12358 0.26346 0.05892 0.22259 0.04977 58365.364613 0.000312 0.24656 0.06257 0.96296 0 1.80823 0.20586 1.54191 0.17551 0.44584 0.10112 0.38051 0.08628 58365.365319 0.000394 0.23157 0.05070 0.96324 0 2.03774 0.19827 1.71762 0.16712 0.47188 0.09255 0.39761 0.07798 58365.366193 0.000480 0.19882 0.04465 0.98795 0 1.75062 0.16379 1.47722 0.13820 0.34806 0.07105 0.29317 0.05984
