/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 55216.326073 0.000211 0.27182 0.01617 1.00000 0 39.76739 1.09522 36.62911 1.00875 10.80962 0.56996 9.94686 0.52443 55216.326854 0.000570 0.26007 0.00935 1.00000 0 42.25914 0.68880 38.87710 0.63365 10.99026 0.35227 10.10231 0.32381 55216.327725 0.000301 0.27053 0.01348 1.00000 0 39.60896 0.91434 36.78956 0.84926 10.71554 0.47328 9.95280 0.43959 55216.328153 0.000127 0.25948 0.02083 1.00000 0 37.95538 1.38354 35.25329 1.28504 9.84876 0.70423 9.14761 0.65409 55216.328405 0.000124 0.24774 0.01978 1.00000 0 40.89594 1.46898 37.48262 1.34639 10.13175 0.72232 9.29250 0.66247 55216.328674 0.000145 0.21680 0.01723 1.00000 0 39.90774 1.33697 36.82033 1.23344 8.65182 0.62350 7.97890 0.57504 55216.328940 0.000122 0.26356 0.02065 1.00000 0 41.18329 1.48762 37.71704 1.36234 10.85414 0.75461 9.93215 0.69055 55216.329232 0.000171 0.24671 0.01638 1.00000 0 43.47719 1.29084 39.74675 1.18002 10.72630 0.63716 9.80997 0.58258 55216.329522 0.000119 0.25952 0.02106 1.00000 0 39.93379 1.47462 37.06872 1.36882 10.36363 0.74877 9.62150 0.69512 55216.329785 0.000145 0.27016 0.01957 1.00000 0 39.57392 1.32853 36.55637 1.22720 10.69114 0.68645 9.88382 0.63451 55216.330063 0.000133 0.23582 0.01859 1.00000 0 40.57680 1.40954 37.44245 1.30049 9.56874 0.67706 8.81712 0.62384 55216.330757 0.000561 0.26564 0.00962 1.00000 0 41.92566 0.69292 38.37403 0.63416 11.13693 0.35891 10.19332 0.32846 55216.331883 0.000564 0.28056 0.01012 1.00000 0 39.74567 0.67330 36.43486 0.61718 11.15098 0.35512 10.22827 0.32572 55216.332569 0.000122 0.24291 0.01892 1.00000 0 44.57825 1.54875 40.68646 1.41344 10.82866 0.75472 9.88446 0.68890 55216.333356 0.000666 0.27499 0.00911 0.99595 0 40.98517 0.63087 37.56361 0.57817 11.27038 0.33076 10.33221 0.30320
