/* ** ** 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 58256.037837 0.000428 0.12427 0.02951 0.97973 0 2.67140 0.21346 2.21310 0.17680 0.33198 0.07424 0.27632 0.06179 58256.038740 0.000475 0.10856 0.02559 0.98780 0 2.75706 0.20595 2.27003 0.16955 0.29930 0.06693 0.24733 0.05530 58256.039597 0.000382 0.13737 0.03280 0.97727 0 2.72774 0.22847 2.26095 0.18937 0.37472 0.08379 0.31059 0.06945 58256.040277 0.000298 0.17288 0.04194 0.98058 0 2.76762 0.26052 2.29471 0.21600 0.47846 0.10699 0.39670 0.08870 58256.040873 0.000298 0.18869 0.04613 0.98058 0 2.53453 0.25043 2.10243 0.20774 0.47823 0.10694 0.39670 0.08870 58256.041689 0.000518 0.11991 0.02837 0.95531 0 2.35859 0.18206 1.95399 0.15083 0.28282 0.06324 0.23431 0.05239 58256.042548 0.000341 0.16965 0.04160 0.95763 0 2.48294 0.23098 2.06414 0.19202 0.42123 0.09557 0.35002 0.07942 58256.043251 0.000362 0.15707 0.03891 0.96000 0 2.49587 0.22813 2.07137 0.18933 0.39203 0.09026 0.32532 0.07491 58256.043966 0.000353 0.13899 0.03360 0.95902 0 2.93449 0.24467 2.43240 0.20281 0.40786 0.09254 0.33806 0.07670 58256.044631 0.000312 0.17659 0.04194 0.98148 0 2.70970 0.25395 2.24778 0.21066 0.47852 0.10442 0.39689 0.08661 58256.045251 0.000307 0.17499 0.04237 0.95283 0 2.73107 0.25343 2.26756 0.21042 0.47792 0.10687 0.39670 0.08870 58256.046130 0.000573 0.25192 0.03998 0.99495 0 2.43263 0.17511 2.01771 0.14524 0.61284 0.08667 0.50846 0.07191 58256.047632 0.000929 0.09642 0.01805 0.99065 0 2.53455 0.14079 2.10556 0.11696 0.24438 0.04369 0.20304 0.03630
