/* ** ** 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 59222.134086 0.000706 0.14317 0.01097 0.98361 0 14.07114 0.38167 11.54015 0.31287 2.01451 0.14441 1.65433 0.11853 59222.135431 0.000639 0.14349 0.01135 0.99548 0 14.80445 0.41202 12.28693 0.34189 2.12424 0.15735 1.76350 0.13061 59222.136733 0.000663 0.14805 0.01151 0.99127 0 14.02738 0.39054 11.70691 0.32587 2.07679 0.15077 1.73309 0.12583 59222.138085 0.000689 0.14487 0.01114 0.97899 0 14.12485 0.38258 11.75386 0.31832 2.04623 0.14730 1.70485 0.12264 59222.139387 0.000613 0.16518 0.01294 0.98585 0 13.76741 0.40503 11.39864 0.33529 2.27414 0.16511 1.88235 0.13666 59222.140631 0.000631 0.15404 0.01247 0.99083 0 13.84806 0.40265 11.49337 0.33413 2.13315 0.16120 1.77097 0.13382 59222.142517 0.001256 0.14533 0.00819 0.97811 0 14.31482 0.28491 12.07573 0.24034 2.08031 0.10965 1.75398 0.09245 59222.869030 0.000582 0.15897 0.01239 0.99005 0 14.02167 0.40363 12.50492 0.35996 2.22904 0.16137 1.98708 0.14388 59222.870161 0.000550 0.16829 0.01311 0.98421 0 14.12103 0.41586 12.55881 0.36985 2.37642 0.17139 2.11356 0.15243 59222.871264 0.000553 0.16772 0.01299 0.99476 0 14.00753 0.41250 12.45905 0.36690 2.34938 0.16832 2.08972 0.14972 59222.872392 0.000576 0.16052 0.01247 0.99497 0 13.97669 0.40475 12.43607 0.36014 2.24349 0.16180 1.99614 0.14396 59222.873622 0.000654 0.16122 0.01228 0.97345 0 13.51903 0.37434 12.02282 0.33291 2.17958 0.15472 1.93839 0.13760
