/* ** ** 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 59240.257107 0.000700 0.12342 0.01219 0.98760 0 9.09151 0.29742 7.97887 0.26101 1.12205 0.10457 0.98441 0.09175 59240.258401 0.000593 0.12771 0.01383 0.98049 0 8.72322 0.31706 7.68225 0.27922 1.11407 0.11363 0.98115 0.10007 59240.259353 0.000359 0.10560 0.01592 0.98387 0 8.74202 0.41059 7.69491 0.36141 0.92316 0.13228 0.81251 0.11643 59240.260172 0.000460 0.07892 0.01206 0.99371 0 8.83513 0.36517 7.78181 0.32163 0.69728 0.10260 0.61420 0.09038 59240.260962 0.000330 0.12459 0.01897 0.99123 0 7.99193 0.41083 7.04043 0.36192 0.99572 0.14268 0.87722 0.12570 59240.261902 0.000611 0.10465 0.01180 0.97474 0 9.45203 0.33131 8.32495 0.29180 0.98913 0.10596 0.87121 0.09333 59240.324181 0.001102 0.13587 0.01041 0.98163 0 8.98091 0.23776 7.78640 0.20612 1.22022 0.08771 1.05749 0.07600 59240.325706 0.000422 0.08553 0.01250 0.99315 0 9.57791 0.40003 8.24574 0.34435 0.81920 0.11472 0.70462 0.09867 59240.326453 0.000324 0.10880 0.01663 0.99107 0 9.40302 0.44943 8.10831 0.38750 1.02306 0.14849 0.88378 0.12830 59240.327153 0.000376 0.10362 0.01562 0.96923 0 8.75508 0.40903 7.57993 0.35413 0.90720 0.13001 0.78677 0.11272 59240.327836 0.000307 0.13612 0.02056 0.97170 0 8.28311 0.43052 7.20898 0.37469 1.12752 0.15991 0.98191 0.13926 59240.328464 0.000321 0.10014 0.01488 1.00000 0 10.43149 0.47424 8.96629 0.40761 1.04461 0.14774 0.90240 0.12762 59240.329314 0.000530 0.11561 0.01379 0.98361 0 8.87628 0.34169 7.68244 0.29568 1.02620 0.11587 0.89002 0.10050
