/* ** ** 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 57538.253802 0.000179 0.25532 0.02060 1.00000 0 27.58554 1.00657 24.98463 0.91164 7.04306 0.50681 6.37764 0.45892 57538.254161 0.000179 0.26313 0.02104 1.00000 0 27.16469 0.99788 24.47934 0.89923 7.14776 0.50763 6.44118 0.45745 57538.254511 0.000171 0.26210 0.02096 0.98305 0 29.41096 1.07421 26.26594 0.95926 7.70864 0.54852 6.89730 0.49074 57538.254876 0.000194 0.23692 0.01873 1.00000 0 28.25508 0.98032 25.54082 0.88614 6.69409 0.47558 6.05120 0.42990 57538.255252 0.000182 0.28261 0.02272 0.98413 0 25.79518 0.96640 23.33238 0.87413 7.29002 0.51840 6.59378 0.46889 57538.255620 0.000185 0.22960 0.01840 1.00000 0 30.44268 1.04665 27.27679 0.93779 6.98974 0.50609 6.26357 0.45347 57538.255990 0.000185 0.26516 0.02159 1.00000 0 25.74771 0.95953 23.27013 0.86720 6.82719 0.49429 6.16861 0.44662 57538.256337 0.000162 0.28852 0.02362 0.98214 0 27.65299 1.06622 25.00446 0.96410 7.97855 0.57616 7.21444 0.52098 57538.256658 0.000159 0.28720 0.02335 0.98182 0 28.33346 1.08230 25.62494 0.97884 8.13743 0.58404 7.35958 0.52821 57538.257008 0.000191 0.24869 0.01981 1.00000 0 26.96593 0.96614 24.37254 0.87322 6.70623 0.47714 6.06127 0.43125 57538.257359 0.000159 0.30070 0.02441 0.98182 0 27.24579 1.06501 24.63731 0.96304 8.19269 0.58290 7.40821 0.52709 57538.257694 0.000177 0.26540 0.02119 1.00000 0 27.59827 1.01892 24.95748 0.92143 7.32465 0.51853 6.62377 0.46891 57538.258053 0.000182 0.27124 0.02160 1.00000 0 26.63218 0.98622 24.07773 0.89162 7.22360 0.50935 6.53080 0.46050 57538.258403 0.000168 0.27977 0.02258 1.00000 0 27.27791 1.04023 24.65430 0.94018 7.63145 0.54297 6.89730 0.49074 57538.258733 0.000162 0.27660 0.02236 1.00000 0 28.42180 1.08071 25.69652 0.97708 7.86152 0.56076 7.10786 0.50700 57538.259092 0.000197 0.24781 0.01979 0.98529 0 26.56197 0.94670 24.01511 0.85593 6.58236 0.47037 5.95120 0.42527 57538.259494 0.000205 0.26776 0.02009 0.97357 0 27.45620 0.94603 24.82780 0.85547 7.35165 0.48998 6.64783 0.44307
