/* ** ** 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 56716.310920 0.000477 0.13570 0.01636 0.98788 0 12.19115 0.50824 7.20315 0.29980 1.65439 0.18714 0.98273 0.11098 56716.311779 0.000382 0.11340 0.01695 1.00000 0 11.97688 0.57797 6.77700 0.32678 1.35818 0.19217 0.75884 0.10732 56716.312514 0.000353 0.12310 0.01846 0.96721 0 12.50391 0.62434 6.86536 0.34275 1.53924 0.21770 0.84887 0.12005 56716.313226 0.000359 0.12253 0.01863 0.97581 0 12.26050 0.60960 6.77087 0.33648 1.50222 0.21581 0.82715 0.11886 56716.313935 0.000350 0.10347 0.01581 1.00000 0 14.04718 0.65917 7.80722 0.36623 1.45346 0.21129 0.81060 0.11770 56716.314612 0.000327 0.14740 0.02157 0.98230 0 11.97481 0.63339 6.67192 0.35290 1.76508 0.24084 0.98325 0.13418 56716.315379 0.000440 0.10248 0.01561 0.98684 0 11.31381 0.52221 6.38407 0.29460 1.15948 0.16832 0.65388 0.09495 56716.316163 0.000344 0.12421 0.01889 0.99160 0 11.97933 0.60929 6.76032 0.34379 1.48794 0.21321 0.84004 0.12037 56716.316834 0.000327 0.15320 0.02333 0.96460 0 10.88723 0.60474 6.08715 0.33804 1.66788 0.23649 0.92778 0.13160 56716.317575 0.000414 0.09472 0.01403 0.98601 0 13.47137 0.59101 7.49410 0.32877 1.27596 0.18046 0.71040 0.10047 56716.318449 0.000460 0.09652 0.01468 0.96226 0 11.88841 0.53445 6.67119 0.29988 1.14742 0.16672 0.64106 0.09309 56716.319244 0.000336 0.12358 0.01902 0.98276 0 12.55339 0.63511 7.00810 0.35440 1.55131 0.22552 0.86037 0.12493 56716.319890 0.000310 0.13617 0.02038 0.98131 0 12.55459 0.64988 7.20968 0.37321 1.70952 0.24011 0.98220 0.13794 56716.320842 0.000642 0.12796 0.01423 0.97748 0 11.82556 0.44202 6.73328 0.25162 1.51316 0.15854 0.86263 0.09037
