/* ** ** 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 55297.088046 0.000333 0.11706 0.01829 0.98261 0 10.16681 0.50733 7.51862 0.36805 1.19009 0.17620 0.86832 0.12601 55297.088677 0.000298 0.11671 0.01790 1.00000 0 9.98816 0.49614 8.13106 0.40386 1.16573 0.16911 0.95262 0.13825 55297.089290 0.000315 0.11419 0.01675 0.98165 0 11.18235 0.52352 8.60490 0.40283 1.27690 0.17752 0.98274 0.13664 55297.090425 0.000819 0.17541 0.01374 0.98940 0 10.27344 0.30976 8.01132 0.24155 1.80208 0.13033 1.40537 0.10164 55297.092158 0.000914 0.15943 0.01230 0.98734 0 10.27436 0.29348 7.99518 0.22837 1.63802 0.11740 1.27421 0.09133 55297.094160 0.001088 0.13404 0.01022 0.98138 0 10.35577 0.26933 8.04069 0.20911 1.38808 0.09949 1.07738 0.07722 55297.096217 0.000969 0.14847 0.01146 0.98806 0 10.25848 0.28244 8.02670 0.22099 1.52310 0.10980 1.19192 0.08593 55297.098579 0.001392 0.13439 0.00889 0.97713 0 10.66367 0.24129 8.30828 0.18799 1.43307 0.08906 1.11657 0.06939
