/* ** ** 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 57840.324252 0.000602 0.15239 0.01170 0.98077 0 14.48461 0.40170 12.75302 0.35365 2.20733 0.15800 1.94577 0.13928 57840.325343 0.000489 0.18620 0.01454 1.00000 0 14.29160 0.44228 12.64093 0.39119 2.66109 0.19077 2.35324 0.16870 57840.326382 0.000550 0.15917 0.01241 0.99474 0 14.71716 0.42319 13.07050 0.37584 2.34260 0.16976 2.08046 0.15077 57840.327432 0.000501 0.18469 0.01444 0.97688 0 14.28196 0.43898 12.67732 0.38966 2.63778 0.18959 2.34139 0.16829 57840.328503 0.000570 0.15770 0.01221 1.00000 0 14.37399 0.41088 12.76089 0.36477 2.26681 0.16317 2.01246 0.14486 57840.329623 0.000550 0.16445 0.01273 0.97895 0 14.57126 0.42001 12.93635 0.37288 2.39622 0.17223 2.12739 0.15290 57840.330739 0.000567 0.16025 0.01243 0.96939 0 14.72251 0.41842 13.07078 0.37148 2.35923 0.17033 2.09460 0.15122 57840.331897 0.000590 0.15386 0.01183 0.99020 0 14.38486 0.40481 12.77142 0.35940 2.21327 0.15843 1.96504 0.14066 57840.333103 0.000616 0.14183 0.01089 0.98592 0 14.95917 0.40266 13.28499 0.35759 2.12170 0.15250 1.88426 0.13543 57840.334223 0.000503 0.18022 0.01400 0.98276 0 14.49657 0.43840 12.87935 0.38949 2.61262 0.18701 2.32127 0.16616 57840.335404 0.000677 0.14963 0.01054 0.97863 0 15.50704 0.39244 13.77019 0.34849 2.32031 0.15248 2.06035 0.13540
