/* ** ** 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 55586.244641 0.000347 0.11407 0.02572 0.96667 0 11.13540 0.78515 3.50059 0.24571 1.27019 0.27202 0.38845 0.08306 55586.245338 0.000350 0.09438 0.02243 0.96694 0 10.74944 0.75822 3.56947 0.25151 1.01449 0.23028 0.33810 0.07670 55586.246018 0.000330 0.09491 0.02253 0.98246 0 10.61170 0.74166 3.72420 0.26026 1.00717 0.22847 0.35320 0.08012 55586.246669 0.000321 0.09335 0.02276 0.96396 0 10.97614 0.76687 3.85300 0.26918 1.02460 0.23934 0.36020 0.08413 55586.247491 0.000501 0.06096 0.01424 0.96532 0 11.08739 0.61543 3.88267 0.21552 0.67594 0.15332 0.23688 0.05373 55586.248455 0.000463 0.07242 0.01677 0.90626 0 10.75635 0.65016 3.81478 0.23059 0.77894 0.17418 0.27632 0.06179 55586.249291 0.000373 0.07443 0.01775 0.98450 0 11.73920 0.73330 4.13566 0.25834 0.87372 0.20111 0.30748 0.07077 55586.249965 0.000301 0.09771 0.02324 0.97115 0 11.15588 0.79556 4.02070 0.28672 1.09003 0.24728 0.39167 0.08885 55586.250599 0.000333 0.08904 0.02077 0.95652 0 11.44929 0.75840 4.09346 0.27112 1.01940 0.22797 0.36424 0.08145 55586.251542 0.000611 0.11528 0.01794 0.98104 0 11.37508 0.56914 4.05125 0.20268 1.31131 0.19320 0.46670 0.06874 55586.252471 0.000318 0.10553 0.02516 0.95455 0 9.86026 0.72389 3.56093 0.26143 1.04060 0.23605 0.37674 0.08546 55586.253119 0.000330 0.08749 0.02099 0.99123 0 10.97301 0.74211 3.94817 0.26701 0.96007 0.22094 0.34557 0.07954 55586.253782 0.000327 0.07612 0.01818 0.98230 0 12.91384 0.82134 4.61234 0.29336 0.98305 0.22629 0.35180 0.08097 55586.254433 0.000324 0.08831 0.02090 0.96429 0 11.71999 0.79164 4.14763 0.28016 1.03502 0.23473 0.36628 0.08309 55586.255136 0.000379 0.10122 0.02148 0.93893 0 11.42068 0.71297 4.04860 0.25273 1.15604 0.23443 0.41107 0.08336
