/* ** ** 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 55230.101587 0.000480 0.18129 0.01404 0.98795 0 14.94435 0.45213 13.38904 0.40506 2.70930 0.19314 2.42792 0.17309 55230.102640 0.000567 0.14507 0.01115 0.98980 0 15.83420 0.42979 14.04829 0.38128 2.29702 0.16510 2.03964 0.14660 55230.103690 0.000483 0.17964 0.01405 0.97605 0 15.15656 0.45666 13.47644 0.40600 2.72271 0.19649 2.41991 0.17465 55230.104691 0.000518 0.15617 0.01213 1.00000 0 15.92238 0.45214 14.13658 0.40143 2.48655 0.17975 2.20784 0.15958 55230.105736 0.000527 0.16963 0.01307 0.98352 0 14.69077 0.42948 13.12750 0.38376 2.49195 0.17765 2.22446 0.15858 55230.106778 0.000515 0.17100 0.01354 0.97753 0 14.71469 0.43655 13.07485 0.38786 2.51625 0.18465 2.23832 0.16423 55230.107793 0.000501 0.16506 0.01268 0.98844 0 15.93739 0.45829 14.19118 0.40807 2.63058 0.18735 2.34468 0.16698 55230.108806 0.000512 0.16506 0.01285 0.99435 0 15.19298 0.44282 13.58012 0.39581 2.50769 0.18097 2.24116 0.16175 55230.109839 0.000521 0.16209 0.01246 0.98889 0 15.47486 0.44353 13.78052 0.39496 2.50834 0.17884 2.23696 0.15947 55230.110875 0.000515 0.15951 0.01238 0.98315 0 15.80682 0.45093 14.13173 0.40315 2.52129 0.18199 2.25397 0.16267 55230.112287 0.000897 0.16358 0.00959 0.99032 0 15.55603 0.33892 13.87100 0.30220 2.54466 0.13842 2.26950 0.12344
