/* ** ** 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 59692.888999 0.000527 0.09136 0.01337 0.97802 0 7.06924 0.30143 6.28558 0.26802 0.64584 0.09044 0.57399 0.08037 59692.890067 0.000541 0.08732 0.01302 0.97326 0 7.13170 0.30561 6.24157 0.26746 0.62273 0.08896 0.54576 0.07797 59692.890915 0.000301 0.06317 0.01459 0.98077 0 7.04637 0.40779 6.18390 0.35791 0.44511 0.09953 0.39281 0.08784 59692.891818 0.000602 0.08167 0.01213 0.96154 0 6.86660 0.28041 6.08394 0.24843 0.56077 0.08011 0.49664 0.07095 59692.892917 0.000498 0.08730 0.01313 0.96512 0 7.73749 0.32840 6.80055 0.28858 0.67550 0.09750 0.59330 0.08563 59692.893869 0.000454 0.09474 0.01431 0.96815 0 7.68570 0.34157 6.83943 0.30396 0.72813 0.10509 0.64795 0.09352 59692.894818 0.000495 0.09279 0.01372 0.97661 0 7.28943 0.31488 6.46400 0.27921 0.67641 0.09566 0.59980 0.08482 59692.895929 0.000616 0.08290 0.01240 0.95362 0 6.98947 0.28088 6.18775 0.24864 0.57940 0.08347 0.51354 0.07396 59692.942375 0.000535 0.07854 0.01155 0.97838 0 7.78563 0.31267 7.03439 0.28250 0.61150 0.08648 0.55341 0.07826 59692.943435 0.000524 0.07968 0.01201 0.97238 0 7.75215 0.31569 7.00753 0.28535 0.61765 0.08967 0.55735 0.08092 59692.944439 0.000480 0.08911 0.01350 0.98193 0 7.49755 0.32403 6.75099 0.29170 0.66811 0.09697 0.60180 0.08737 59692.945347 0.000428 0.09714 0.01476 0.96622 0 7.92497 0.35838 7.05843 0.31918 0.76980 0.11170 0.68597 0.09959 59692.946386 0.000611 0.07274 0.01080 0.98104 0 7.30708 0.28335 6.58167 0.25524 0.53155 0.07615 0.47889 0.06862 59692.947303 0.000307 0.06158 0.01387 1.00000 0 7.11867 0.39687 6.41912 0.35780 0.43838 0.09567 0.39689 0.08661 59692.948165 0.000556 0.07504 0.01102 0.98958 0 7.82178 0.30806 7.04397 0.27741 0.58691 0.08301 0.52719 0.07456 59692.949705 0.000984 0.08143 0.00890 0.97647 0 7.52435 0.22557 6.80826 0.20408 0.61273 0.06443 0.55493 0.05836
