/* ** ** 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 59972.091327 0.000333 0.31509 0.01166 1.00000 0 60.20383 1.08550 54.53765 0.98326 18.96980 0.61297 17.18951 0.55544 59972.091986 0.000327 0.31784 0.01178 1.00000 0 60.27649 1.09340 55.13061 1.00004 19.15852 0.61915 17.52750 0.56643 59972.092637 0.000324 0.32898 0.01217 1.00000 0 58.96288 1.08416 54.19975 0.99658 19.39749 0.62281 17.83053 0.57250 59972.093294 0.000333 0.32483 0.01205 1.00000 0 57.80811 1.06436 53.13811 0.97837 18.77782 0.60478 17.26086 0.55593 59972.093957 0.000330 0.32158 0.01186 1.00000 0 59.15383 1.07609 54.37509 0.98916 19.02269 0.60997 17.48594 0.56069 59972.094619 0.000333 0.31709 0.01180 1.00000 0 58.83789 1.07004 54.08467 0.98360 18.65684 0.60562 17.14965 0.55669 59972.095282 0.000330 0.31600 0.01161 1.00000 0 60.77594 1.09902 55.33655 1.00063 19.20516 0.61398 17.47343 0.55860 59972.095927 0.000315 0.33311 0.01228 1.00000 0 59.92547 1.10949 55.03395 1.01894 19.96205 0.63644 18.33187 0.58445 59972.096570 0.000327 0.33164 0.01225 1.00000 0 57.93704 1.07279 53.25663 0.98612 19.21401 0.61434 17.66182 0.56471 59972.097229 0.000333 0.31694 0.01176 1.00000 0 58.88306 1.06887 54.12657 0.98253 18.66216 0.60365 17.15467 0.55489 59972.097901 0.000339 0.31450 0.01160 1.00000 0 58.63907 1.06114 53.90211 0.97542 18.44172 0.59287 16.95197 0.54497 59972.098558 0.000318 0.33665 0.01249 1.00000 0 58.67134 1.09448 53.93210 1.00607 19.75196 0.63345 18.15647 0.58228 59972.099304 0.000428 0.32929 0.01058 0.99706 0 58.93565 0.94583 54.17531 0.86943 19.40688 0.54003 17.83935 0.49641
