/* ** ** 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 55174.687748 0.000301 0.17301 0.01337 0.98077 0 24.83530 0.73276 22.64598 0.66809 4.29683 0.30699 3.91247 0.27957 55174.688329 0.000281 0.19381 0.01494 0.96907 0 24.46011 0.75978 22.08520 0.68595 4.74073 0.33441 4.28373 0.30215 55174.688922 0.000312 0.15808 0.01209 0.98148 0 26.25770 0.74124 24.05564 0.67908 4.15074 0.29509 3.80263 0.27034 55174.689530 0.000295 0.18119 0.01427 0.99020 0 23.46909 0.71840 21.50152 0.65817 4.25230 0.30864 3.89574 0.28276 55174.690103 0.000278 0.17768 0.01407 1.00000 0 25.07149 0.76510 22.96280 0.70075 4.45458 0.32545 4.07991 0.29808 55174.690644 0.000263 0.20000 0.01581 0.98901 0 24.24245 0.78090 22.05072 0.71017 4.84847 0.35007 4.41641 0.31888 55174.691176 0.000269 0.19169 0.01517 1.00000 0 24.09211 0.76053 22.07178 0.69676 4.61816 0.33520 4.23086 0.30709 55174.691726 0.000281 0.17964 0.01402 0.98969 0 25.14851 0.76215 23.03662 0.69815 4.51771 0.32492 4.13826 0.29763 55174.692276 0.000269 0.18399 0.01440 1.00000 0 25.34258 0.78353 23.21741 0.71782 4.66275 0.33535 4.27175 0.30723 55174.692820 0.000275 0.19231 0.01507 1.00000 0 23.87084 0.75698 21.72827 0.68898 4.59058 0.32886 4.17967 0.29943 55174.693364 0.000269 0.19481 0.01553 1.00000 0 23.59693 0.75402 21.61893 0.69082 4.59680 0.33584 4.21152 0.30770 55174.693919 0.000286 0.18235 0.01422 0.98990 0 24.55452 0.74589 22.46428 0.68237 4.47747 0.32161 4.09677 0.29427 55174.694533 0.000327 0.15523 0.01200 1.00000 0 24.83675 0.70379 22.66854 0.64231 3.85550 0.27730 3.51569 0.25286 55174.695146 0.000286 0.17888 0.01399 1.00000 0 24.61910 0.74964 22.55854 0.68690 4.40380 0.31714 4.03515 0.29060 55174.695737 0.000304 0.17596 0.01385 1.00000 0 23.24861 0.70776 21.29758 0.64836 4.09072 0.29691 3.74734 0.27199 55174.696327 0.000286 0.18282 0.01426 1.00000 0 23.94820 0.73795 21.93903 0.67604 4.37811 0.31364 4.01079 0.28733 55174.696877 0.000263 0.19453 0.01534 1.00000 0 24.50403 0.77608 22.45323 0.71113 4.76670 0.34417 4.36788 0.31538 55174.697429 0.000289 0.18150 0.01424 1.00000 0 23.90428 0.73347 21.89954 0.67196 4.33855 0.31326 3.97477 0.28699 55174.698034 0.000315 0.16604 0.01282 0.99083 0 24.29248 0.70976 22.25431 0.65021 4.03348 0.28822 3.69511 0.26404 55174.698824 0.000475 0.17036 0.01086 0.98780 0 23.84359 0.57152 21.84301 0.52357 4.06210 0.24006 3.72122 0.21992
