/* ** ** 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 59341.222250 0.000437 0.16574 0.01290 1.00000 0 17.11198 0.50206 15.88019 0.46591 2.83608 0.20451 2.63183 0.18979 59341.223167 0.000480 0.16609 0.01294 0.98795 0 15.79375 0.46329 14.49850 0.42524 2.62318 0.18925 2.40764 0.17366 59341.224116 0.000469 0.15788 0.01235 0.98148 0 16.88597 0.48075 15.61189 0.44447 2.66602 0.19421 2.46507 0.17959 59341.225065 0.000480 0.16362 0.01266 0.98795 0 15.91335 0.46001 14.76872 0.42693 2.60372 0.18688 2.41650 0.17343 59341.226072 0.000527 0.14405 0.01117 0.97802 0 16.68776 0.45202 15.38514 0.41672 2.40384 0.17464 2.21320 0.16081 59341.227012 0.000414 0.18237 0.01431 1.00000 0 16.31358 0.50470 15.14103 0.46842 2.97504 0.21459 2.76121 0.19916 59341.227901 0.000475 0.15517 0.01193 0.98780 0 17.07163 0.47982 15.84496 0.44535 2.64903 0.18963 2.45870 0.17601 59341.228887 0.000512 0.14813 0.01160 0.98305 0 16.32298 0.45348 15.14975 0.42089 2.41800 0.17704 2.24421 0.16432 59341.229889 0.000489 0.15592 0.01208 0.98225 0 16.49737 0.46747 15.24454 0.43196 2.57233 0.18554 2.37863 0.17157 59341.230835 0.000457 0.16892 0.01315 0.98101 0 16.24831 0.47613 15.08042 0.44191 2.74471 0.19797 2.54744 0.18374 59341.231795 0.000503 0.15505 0.01200 0.97701 0 16.14113 0.45396 14.97969 0.42130 2.50273 0.18052 2.32266 0.16753 59341.233158 0.000859 0.15725 0.00912 0.98653 0 16.47326 0.35183 15.28960 0.32655 2.59044 0.13961 2.40432 0.12958
