/* ** ** 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 58288.030341 0.000301 0.18114 0.04548 0.99038 0 2.42582 0.23945 2.08384 0.20569 0.43941 0.10144 0.37821 0.08732 58288.031006 0.000365 0.16271 0.04060 0.99206 0 2.22314 0.21047 1.91512 0.18131 0.36172 0.08351 0.31164 0.07195 58288.031932 0.000561 0.10893 0.02778 0.95361 0 2.18081 0.17130 1.84442 0.14488 0.23756 0.05764 0.20156 0.04889 58288.032887 0.000394 0.14935 0.03593 0.97794 0 2.36950 0.20997 2.02042 0.17905 0.35389 0.07914 0.30125 0.06736 58288.033683 0.000402 0.22834 0.05616 0.94245 0 1.61083 0.17206 1.38783 0.14824 0.36782 0.08149 0.31690 0.07021 58288.034441 0.000356 0.17337 0.04350 0.95935 0 2.24106 0.22023 1.90888 0.18756 0.38853 0.08969 0.33013 0.07622 58288.035205 0.000408 0.15993 0.03924 0.95745 0 2.16115 0.20068 1.84115 0.17098 0.34563 0.07850 0.29268 0.06649 58288.036214 0.000602 0.22705 0.04007 0.96635 0 2.05623 0.16114 1.76043 0.13795 0.46687 0.07382 0.39867 0.06304 58288.037201 0.000385 0.19625 0.04835 0.99248 0 1.79541 0.18576 1.54664 0.16002 0.35234 0.07879 0.30354 0.06787 58288.038023 0.000437 0.14105 0.03377 0.95364 0 2.29311 0.19607 1.96448 0.16798 0.32345 0.07233 0.27824 0.06222 58288.038793 0.000333 0.19457 0.04776 0.98261 0 2.11544 0.21409 1.82228 0.18442 0.41161 0.09204 0.35457 0.07928 58288.040048 0.000923 0.09989 0.01937 0.96865 0 2.24640 0.13352 1.92627 0.11449 0.22440 0.04142 0.19270 0.03556
