/* ** ** 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 59250.096695 0.000686 0.18703 0.01472 0.99156 0 10.44689 0.32800 8.98814 0.28220 1.95384 0.14099 1.68144 0.12132 59250.098128 0.000747 0.15954 0.01238 0.99612 0 11.26873 0.32588 9.68952 0.28020 1.79776 0.12942 1.54530 0.11121 59250.099615 0.000741 0.16043 0.01274 0.98438 0 11.19896 0.32400 9.64367 0.27899 1.79660 0.13283 1.54670 0.11436 59250.100989 0.000634 0.20622 0.01615 0.98174 0 10.55094 0.34311 9.13743 0.29714 2.17580 0.15499 1.88444 0.13423 59250.102265 0.000642 0.19308 0.01503 0.98649 0 11.00364 0.34698 9.44270 0.29773 2.12459 0.15124 1.82111 0.12964 59250.103550 0.000642 0.19475 0.01537 0.97748 0 10.82449 0.34564 9.34952 0.29851 2.10802 0.15209 1.82091 0.13139 59250.104916 0.000723 0.16044 0.01248 0.99600 0 11.49346 0.33377 9.89665 0.28740 1.84396 0.13303 1.58690 0.11450 59250.106585 0.000946 0.17356 0.01163 0.98471 0 11.01057 0.28368 9.44125 0.24321 1.91104 0.11824 1.63676 0.10125
