/* ** ** 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 59706.043628 0.000660 0.24388 0.01938 0.98246 0 9.84796 0.34648 7.30700 0.25691 2.40169 0.17109 1.77952 0.12665 59706.044803 0.000515 0.30837 0.02554 0.96629 0 9.72748 0.38789 7.38347 0.29438 2.99966 0.21775 2.28166 0.16558 59706.045893 0.000576 0.29147 0.02417 0.95980 0 9.15886 0.35531 6.99191 0.27115 2.66949 0.19567 2.03855 0.14940 59706.047036 0.000567 0.27688 0.02255 0.97959 0 9.71209 0.36794 7.41823 0.28092 2.68907 0.19391 2.05470 0.14814 59706.048243 0.000639 0.26033 0.02120 0.98643 0 9.20627 0.33952 6.91700 0.25501 2.39666 0.17405 1.80469 0.13105 59706.049533 0.000651 0.27423 0.02230 0.97778 0 8.84165 0.33534 6.58082 0.24954 2.42466 0.17440 1.80229 0.12961 59706.050726 0.000541 0.32653 0.02734 0.99465 0 8.57724 0.35776 6.44714 0.26892 2.80075 0.20330 2.10993 0.15312 59706.052002 0.000735 0.28186 0.01956 0.98425 0 10.27368 0.33686 7.64552 0.25062 2.89579 0.17713 2.15538 0.13180
