/* ** ** 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 56324.659897 0.000501 0.15752 0.01240 0.98266 0 27.64990 0.79792 14.75594 0.42099 4.35548 0.31902 2.32645 0.16922 56324.660889 0.000492 0.16454 0.01312 0.99412 0 26.89903 0.79188 13.95329 0.41062 4.42602 0.32806 2.29479 0.17009 56324.661870 0.000489 0.16834 0.01324 0.97633 0 26.89063 0.79162 14.14967 0.41650 4.52673 0.33011 2.38481 0.17392 56324.662860 0.000501 0.15707 0.01230 0.98844 0 27.96134 0.79886 14.64756 0.41848 4.39202 0.32028 2.30113 0.16782 56324.663872 0.000512 0.15471 0.01207 0.98870 0 27.73844 0.79128 14.55186 0.41501 4.29145 0.31167 2.24758 0.16325 56324.664850 0.000466 0.16601 0.01298 0.99379 0 28.23361 0.82871 14.87904 0.43669 4.68703 0.33968 2.47081 0.17899 56324.665825 0.000509 0.15769 0.01243 0.97159 0 27.30012 0.78074 14.51862 0.41523 4.30504 0.31610 2.29040 0.16816 56324.666777 0.000443 0.17509 0.01401 0.99346 0 27.41919 0.84000 14.64628 0.44863 4.80081 0.35483 2.56462 0.18957 56324.667709 0.000489 0.16832 0.01290 0.99408 0 26.61675 0.78797 14.17059 0.41949 4.48010 0.31682 2.38492 0.16864 56324.668684 0.000486 0.15514 0.01211 1.00000 0 27.81944 0.79284 15.08209 0.42978 4.31587 0.31349 2.34122 0.17005 56324.669633 0.000463 0.16000 0.01263 1.00000 0 28.16450 0.81872 15.30232 0.44477 4.50639 0.33084 2.44786 0.17972 56324.670551 0.000454 0.16735 0.01309 0.98726 0 28.02022 0.82615 15.28094 0.45044 4.68927 0.33963 2.55051 0.18476 56324.671592 0.000587 0.18136 0.01161 0.99015 0 29.68118 0.74557 16.23014 0.40761 5.38292 0.31708 2.94356 0.17331
