/* ** ** 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 58551.862813 0.000538 0.27299 0.00986 1.00000 0 42.84066 0.71780 39.13478 0.65570 11.69523 0.37421 10.68725 0.34195 58551.863890 0.000538 0.26761 0.00964 1.00000 0 43.24189 0.71560 40.02959 0.66244 11.57181 0.37010 10.71100 0.34256 58551.864949 0.000521 0.28800 0.01045 1.00000 0 41.53709 0.71427 38.41473 0.66058 11.96282 0.38215 11.06346 0.35341 58551.866011 0.000541 0.26849 0.00971 1.00000 0 42.50623 0.70807 39.44876 0.65714 11.41255 0.36635 10.59165 0.33999 58551.867073 0.000521 0.28024 0.01013 1.00000 0 42.48648 0.72012 39.43058 0.66832 11.90645 0.38030 11.05005 0.35295 58551.868109 0.000515 0.28221 0.01025 1.00000 0 42.52761 0.72530 39.46898 0.67314 12.00161 0.38506 11.13843 0.35736 58551.869147 0.000524 0.28430 0.01029 1.00000 0 41.73292 0.71235 38.73096 0.66111 11.86459 0.37858 11.01113 0.35135 58551.870186 0.000515 0.28133 0.01019 1.00000 0 42.85797 0.72953 39.77518 0.67706 12.05737 0.38539 11.19008 0.35767 58551.871210 0.000509 0.29022 0.01055 1.00000 0 41.92453 0.72633 38.90888 0.67408 12.16734 0.38907 11.29214 0.36108 58551.871838 0.000119 0.24452 0.01950 1.00000 0 42.93663 1.53306 39.84850 1.42280 10.49868 0.74876 9.74358 0.69491 58551.872487 0.000530 0.27800 0.01003 1.00000 0 42.58365 0.71804 39.39567 0.66426 11.83810 0.37744 10.95228 0.34921 58551.873658 0.000642 0.27646 0.00899 1.00000 0 43.22784 0.65573 40.11845 0.60856 11.95090 0.34384 11.09127 0.31911
