/* ** ** 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 60100.197655 0.000460 0.15342 0.01174 0.99371 0 17.95656 0.50376 16.46977 0.46206 2.75495 0.19610 2.52444 0.17968 60100.198569 0.000454 0.17116 0.01316 0.98726 0 16.30414 0.48147 15.11199 0.44627 2.79065 0.19812 2.58622 0.18361 60100.199431 0.000408 0.17850 0.01381 0.99291 0 17.21063 0.52084 15.96056 0.48301 3.07214 0.21866 2.84901 0.20278 60100.200256 0.000417 0.18048 0.01413 0.97917 0 16.74753 0.50955 15.53180 0.47256 3.02259 0.21798 2.80318 0.20215 60100.201179 0.000506 0.14241 0.01104 0.99429 0 17.12114 0.46702 15.87780 0.43310 2.43823 0.17700 2.26117 0.16414 60100.202163 0.000477 0.15349 0.01185 0.98788 0 17.12169 0.48081 15.87853 0.44590 2.62794 0.18902 2.43713 0.17530 60100.203054 0.000414 0.19145 0.01525 0.97902 0 15.75800 0.50048 14.61108 0.46405 3.01690 0.22045 2.79741 0.20441 60100.203887 0.000420 0.17291 0.01339 0.98621 0 17.40300 0.51882 16.13893 0.48114 3.00921 0.21504 2.79062 0.19942 60100.204770 0.000463 0.14872 0.01172 0.98750 0 17.88878 0.50503 16.59043 0.46837 2.66037 0.19569 2.46729 0.18149 60100.205693 0.000460 0.16278 0.01259 0.99371 0 16.64619 0.48571 15.43787 0.45045 2.70969 0.19413 2.51301 0.18004 60100.206651 0.000498 0.14406 0.01138 0.98256 0 17.18499 0.47464 15.93786 0.44019 2.47567 0.18331 2.29601 0.17001 60100.207736 0.000587 0.17122 0.01132 0.99507 0 17.26790 0.43851 16.01519 0.40670 2.95661 0.18054 2.74212 0.16745
