/* ** ** 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 55657.236473 0.000362 0.11424 0.01629 0.98400 0 16.49409 0.74532 8.65666 0.37709 1.88435 0.25487 0.97655 0.12777 55657.237173 0.000339 0.09591 0.01466 0.98291 0 17.03254 0.77430 8.73012 0.39480 1.63358 0.23847 0.85286 0.12385 55657.238148 0.000637 0.10197 0.01043 0.98636 0 16.38370 0.50986 9.66764 0.30082 1.67072 0.16274 0.98743 0.09618 55657.239778 0.000992 0.12808 0.00975 0.99125 0 15.56266 0.39846 9.12135 0.23349 1.99323 0.14283 1.16615 0.08355 55657.241065 0.000295 0.09197 0.01395 0.99020 0 17.56118 0.76708 10.59927 0.46295 1.61509 0.23463 0.97356 0.14143 55657.242275 0.000914 0.12858 0.00980 0.99684 0 16.39952 0.42307 9.83125 0.25360 2.10868 0.15123 1.26335 0.09060 55657.244199 0.001010 0.11035 0.00844 0.98854 0 17.16287 0.41124 10.32407 0.24737 1.89388 0.13761 1.13998 0.08281 55657.245524 0.000315 0.10290 0.01503 0.98165 0 16.55549 0.73613 9.53278 0.42381 1.70362 0.23700 0.98256 0.13665 55657.246916 0.001076 0.11184 0.00855 0.97043 0 16.55746 0.39486 9.72478 0.23184 1.85180 0.13448 1.08816 0.07902 55657.248311 0.000318 0.10902 0.01663 0.95455 0 14.98189 0.70270 8.55906 0.40133 1.63338 0.23714 0.93405 0.13564 55657.249659 0.001030 0.12920 0.00978 0.96910 0 15.72488 0.39800 9.01482 0.22817 2.03170 0.14498 1.16362 0.08301
