/* ** ** 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 59230.103162 0.000347 0.09254 0.02166 0.99167 0 4.43177 0.30604 3.61691 0.24974 0.41013 0.09171 0.33670 0.07529 59230.103822 0.000312 0.10228 0.02344 0.98148 0 4.67566 0.32720 3.88320 0.27175 0.47822 0.10436 0.39689 0.08661 59230.104710 0.000576 0.13171 0.01985 0.98492 0 4.70537 0.24511 3.88560 0.20237 0.61976 0.08765 0.51105 0.07227 59230.105812 0.000527 0.13967 0.02110 0.96703 0 4.90764 0.26110 4.07449 0.21676 0.68544 0.09694 0.56913 0.08049 59230.106660 0.000315 0.09129 0.02082 0.97248 0 5.25943 0.34857 4.35956 0.28889 0.48012 0.10478 0.39689 0.08661 59230.107499 0.000524 0.13346 0.02022 0.98895 0 5.03736 0.26245 4.17150 0.21734 0.67227 0.09563 0.55669 0.07919 59230.108330 0.000307 0.09425 0.02157 1.00000 0 5.09780 0.35174 4.19912 0.28971 0.48048 0.10486 0.39689 0.08661 59230.109233 0.000596 0.11365 0.01727 0.99515 0 5.12524 0.24938 4.23107 0.20586 0.58250 0.08386 0.48101 0.06924 59230.110202 0.000373 0.09305 0.01992 0.97674 0 5.04168 0.31457 4.18885 0.26136 0.46911 0.09606 0.38924 0.07971 59230.110934 0.000359 0.09405 0.02012 0.97581 0 5.12400 0.32821 4.22606 0.27069 0.48189 0.09838 0.39736 0.08111 59230.111762 0.000469 0.16731 0.02613 0.95679 0 4.55860 0.26619 3.78724 0.22115 0.76270 0.11045 0.63282 0.09164 59230.112528 0.000298 0.09667 0.02300 0.98058 0 4.85666 0.34636 4.05009 0.28884 0.46950 0.10654 0.39155 0.08885 59230.113527 0.000700 0.10164 0.01519 0.98347 0 4.96586 0.22815 4.11412 0.18901 0.50472 0.07180 0.41868 0.05956 59230.114736 0.000509 0.11495 0.01987 0.97727 0 4.66016 0.26142 3.82461 0.21453 0.53569 0.08759 0.43957 0.07186
