/* ** ** 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 58585.015931 0.000396 0.33495 0.01244 1.00000 0 47.11448 0.87482 43.14479 0.80109 15.78102 0.50739 14.44790 0.46450 58585.016692 0.000365 0.36440 0.01368 1.00000 0 47.10153 0.91212 43.18195 0.83621 17.16360 0.55217 15.74376 0.50647 58585.017430 0.000373 0.35888 0.01348 1.00000 0 46.35233 0.89235 42.77000 0.82339 16.63487 0.53656 15.34924 0.49509 58585.018191 0.000388 0.33972 0.01267 1.00000 0 47.03706 0.88343 43.40046 0.81513 15.97948 0.51512 14.74404 0.47529 58585.018952 0.000373 0.35775 0.01344 1.00000 0 46.45321 0.89277 42.86121 0.82373 16.61876 0.53632 15.33371 0.49485 58585.019698 0.000373 0.36907 0.01384 1.00000 0 45.38079 0.88194 41.87250 0.81376 16.74879 0.53697 15.45394 0.49546 58585.020442 0.000370 0.36236 0.01358 1.00000 0 46.39160 0.89833 42.80079 0.82880 16.81054 0.53918 15.50937 0.49744 58585.021206 0.000394 0.33601 0.01249 1.00000 0 47.18288 0.87940 43.33240 0.80764 15.85410 0.51012 14.55540 0.46834 58585.021993 0.000394 0.33340 0.01241 1.00000 0 47.38187 0.87891 43.71695 0.81092 15.79706 0.50969 14.57521 0.47027 58585.022763 0.000376 0.34112 0.01269 1.00000 0 48.47760 0.90713 44.72882 0.83698 16.53680 0.53154 15.25801 0.49044 58585.023567 0.000428 0.29758 0.01087 1.00000 0 49.10798 0.85896 45.11003 0.78903 14.61337 0.46883 13.42822 0.43083 58585.024400 0.000405 0.32096 0.01180 1.00000 0 47.96739 0.87077 44.25798 0.80343 15.39546 0.49207 14.20492 0.45402 58585.025190 0.000385 0.34546 0.01300 1.00000 0 46.64994 0.88218 43.04107 0.81394 16.11588 0.52417 14.86916 0.48362 58585.026307 0.000732 0.34270 0.00928 1.00000 0 46.92663 0.64125 43.23177 0.59075 16.08168 0.37596 14.81571 0.34633
