/* ** ** 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 56391.128481 0.000321 0.19923 0.05024 0.95495 0 3.88088 0.42836 1.68546 0.17756 0.77320 0.17531 0.39689 0.08661 56391.129158 0.000356 0.22855 0.05870 0.96748 0 4.00598 0.44746 1.39517 0.15518 0.91556 0.21173 0.32797 0.07554 56391.129884 0.000370 0.24182 0.06301 0.94531 0 3.31511 0.37922 1.30960 0.14969 0.80166 0.18767 0.31826 0.07441 56391.130596 0.000341 0.19376 0.04887 0.98305 0 4.79775 0.49241 1.73836 0.17839 0.92959 0.21416 0.33645 0.07749 56391.131302 0.000365 0.22787 0.06001 0.96825 0 3.80544 0.43356 1.37106 0.15614 0.86713 0.20588 0.31140 0.07393 56391.131968 0.000301 0.29685 0.07639 0.97115 0 3.61143 0.45948 1.33559 0.16981 1.07206 0.23978 0.39670 0.08870 56391.132810 0.000541 0.22116 0.04563 0.98223 0 3.87957 0.34852 1.42277 0.12780 0.85802 0.15937 0.31630 0.05874 56391.192799 0.000579 0.29894 0.04851 0.94000 0 4.98220 0.38843 1.79067 0.13952 1.48937 0.21198 0.53002 0.07540 56391.193803 0.000425 0.34629 0.05893 0.92517 0 5.77032 0.49099 2.05260 0.17461 1.99822 0.29448 0.70965 0.10465 56391.194862 0.000634 0.23444 0.03714 0.94521 0 5.61079 0.38926 2.03228 0.14092 1.31538 0.18736 0.48137 0.06848 56391.196011 0.000515 0.28890 0.04724 0.96629 0 5.56555 0.43175 1.98452 0.15395 1.60787 0.23145 0.57326 0.08253 56391.197012 0.000486 0.39121 0.06574 0.95238 0 4.42638 0.39568 1.59761 0.14279 1.73163 0.24641 0.62278 0.08860 56391.198386 0.000888 0.21359 0.02866 0.96743 0 6.10532 0.34824 2.15380 0.12280 1.30405 0.15839 0.46191 0.05609
