/* ** ** 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 58712.255041 0.000330 0.19311 0.04930 0.99123 0 3.82187 0.40294 1.76860 0.18120 0.73806 0.17162 0.35457 0.07928 58712.255830 0.000460 0.18259 0.04514 0.96855 0 3.09185 0.29937 1.42096 0.13711 0.56454 0.12843 0.25683 0.05827 58712.256811 0.000521 0.23704 0.04470 0.97778 0 3.38067 0.28217 1.67517 0.13975 0.80136 0.13552 0.39839 0.06734 58712.258024 0.000692 0.25584 0.04063 0.95397 0 3.63772 0.26243 1.71390 0.12360 0.93069 0.13166 0.43933 0.06213 58712.259008 0.000292 0.30073 0.07728 1.00000 0 2.82011 0.35702 1.32310 0.16747 0.84808 0.18965 0.39670 0.08870 58712.259670 0.000370 0.25502 0.05751 0.98438 0 3.25687 0.33932 1.55156 0.16165 0.83056 0.16613 0.39749 0.07950 58712.260414 0.000373 0.17365 0.04216 0.94574 0 4.03583 0.38135 1.89073 0.17867 0.70084 0.15672 0.32842 0.07344 58712.261438 0.000651 0.27037 0.04456 0.96889 0 3.44410 0.26623 1.65002 0.12752 0.93117 0.13554 0.44766 0.06520 58712.262755 0.000666 0.24175 0.03820 0.97826 0 3.76055 0.26450 1.81667 0.12770 0.90910 0.12864 0.44519 0.06296 58712.264103 0.000683 0.30690 0.05079 0.96610 0 2.91883 0.23378 1.40934 0.11284 0.89580 0.12973 0.43028 0.06229 58712.265356 0.000570 0.23602 0.04484 0.95939 0 3.23744 0.27124 1.56276 0.13088 0.76410 0.13029 0.36826 0.06277
