/* ** ** 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 55845.825858 0.000310 0.11901 0.01800 0.97196 0 9.00044 0.43765 8.03123 0.39051 1.07115 0.15341 0.95340 0.13656 55845.826640 0.000472 0.06871 0.01030 0.98160 0 9.92833 0.37223 8.92748 0.33471 0.68215 0.09896 0.61338 0.08899 55845.827421 0.000310 0.11498 0.01742 0.97196 0 9.31480 0.44921 8.37457 0.40386 1.07104 0.15378 0.96293 0.13825 55845.828086 0.000356 0.08708 0.01315 0.97561 0 10.44639 0.43970 9.39177 0.39531 0.90969 0.13197 0.81784 0.11865 55845.828888 0.000446 0.08378 0.01247 0.95455 0 8.95092 0.36363 8.05174 0.32710 0.74988 0.10741 0.67452 0.09661 55845.829759 0.000425 0.07973 0.01186 0.97959 0 9.60650 0.38637 8.63651 0.34736 0.76590 0.10970 0.68857 0.09862 55845.830537 0.000353 0.08797 0.01364 0.98361 0 10.12431 0.43803 9.10542 0.39394 0.89062 0.13260 0.80096 0.11925 55845.831321 0.000425 0.07798 0.01173 0.98639 0 9.65237 0.38519 8.68020 0.34640 0.75267 0.10919 0.67683 0.09819 55845.832048 0.000301 0.11396 0.01721 0.97115 0 9.58223 0.45997 8.61498 0.41354 1.09195 0.15640 0.98172 0.14061 55845.832719 0.000370 0.11460 0.01611 0.96094 0 9.32179 0.40985 8.38236 0.36854 1.06831 0.14266 0.96058 0.12827 55845.833448 0.000359 0.09693 0.01470 0.95968 0 9.46261 0.41790 8.50892 0.37578 0.91718 0.13306 0.82471 0.11965 55845.834119 0.000312 0.11880 0.01777 0.97222 0 8.92602 0.43555 8.03080 0.39187 1.06041 0.14996 0.95397 0.13491 55845.834889 0.000457 0.07714 0.01160 0.96203 0 9.30849 0.36640 8.36962 0.32944 0.71809 0.10418 0.64566 0.09367 55845.835647 0.000301 0.11967 0.01792 0.97115 0 9.20786 0.45229 8.28721 0.40706 1.10194 0.15584 0.99175 0.14025 55845.836275 0.000327 0.10383 0.01600 0.97345 0 9.45789 0.43964 8.50353 0.39528 0.98205 0.14432 0.88298 0.12976 55845.836932 0.000330 0.11052 0.01710 0.95614 0 9.05898 0.42856 8.14462 0.38531 1.00123 0.14745 0.90017 0.13256 55845.838054 0.000793 0.07845 0.00850 0.98905 0 9.69258 0.28266 8.71715 0.25421 0.76034 0.07938 0.68375 0.07139
