/* ** ** 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 58280.990211 0.000466 0.14003 0.03400 0.96894 0 2.20405 0.18964 1.80034 0.15484 0.30863 0.07008 0.25349 0.05753 58280.991039 0.000362 0.19340 0.04728 0.96000 0 2.09472 0.20705 1.72280 0.17029 0.40513 0.09059 0.33389 0.07466 58280.991855 0.000454 0.12708 0.03023 0.97452 0 2.51081 0.20372 2.06071 0.16721 0.31907 0.07135 0.26187 0.05856 58280.992801 0.000492 0.14118 0.03380 0.97059 0 2.10498 0.18021 1.71766 0.14703 0.29718 0.06646 0.24283 0.05430 58280.993793 0.000501 0.12350 0.03013 0.97688 0 2.29604 0.18490 1.87322 0.15083 0.28356 0.06531 0.23091 0.05319 58280.994829 0.000535 0.13225 0.03194 0.98378 0 2.01412 0.16609 1.64581 0.13571 0.26638 0.06047 0.21728 0.04931 58280.995787 0.000422 0.14728 0.03579 0.95890 0 2.34211 0.20360 1.91689 0.16663 0.34495 0.07828 0.28246 0.06410 58280.996533 0.000324 0.18962 0.04630 0.98214 0 2.35578 0.23095 1.92498 0.18869 0.44671 0.09989 0.36424 0.08145 58280.997349 0.000492 0.12786 0.03082 0.96471 0 2.31404 0.18723 1.88988 0.15291 0.29586 0.06717 0.24113 0.05472 58280.998365 0.000524 0.14632 0.03428 0.96133 0 2.04572 0.17450 1.65552 0.14118 0.29932 0.06532 0.24178 0.05276 58280.999430 0.000541 0.18006 0.03644 0.96257 0 2.21833 0.17850 1.79523 0.14445 0.39943 0.07418 0.32276 0.05993
