/* ** ** 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 59349.275339 0.000422 0.16745 0.01311 0.98630 0 18.06734 0.52948 16.33439 0.47868 3.02530 0.21969 2.73723 0.19871 59349.276190 0.000428 0.16935 0.01315 1.00000 0 17.60042 0.52219 15.80647 0.46894 2.98059 0.21386 2.67846 0.19215 59349.277044 0.000425 0.17420 0.01363 0.98639 0 17.28516 0.51924 15.65865 0.47035 3.01109 0.21761 2.72813 0.19709 59349.277917 0.000448 0.16430 0.01299 0.98065 0 17.27877 0.50392 15.59153 0.45466 2.83897 0.20866 2.56133 0.18825 59349.278817 0.000451 0.16191 0.01251 0.98718 0 17.81611 0.51320 16.00314 0.46097 2.88468 0.20685 2.59091 0.18580 59349.279726 0.000457 0.15696 0.01209 1.00000 0 17.90128 0.51007 16.09433 0.45857 2.80974 0.20104 2.52162 0.18043 59349.280701 0.000518 0.16249 0.01175 0.99887 0 17.75098 0.47887 16.03203 0.43247 2.88441 0.19350 2.60649 0.17484
