/* ** ** 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 57424.324800 0.000735 0.15028 0.01152 0.98425 0 11.98312 0.33087 10.62080 0.29320 1.80087 0.12874 1.59593 0.11409 57424.326348 0.000813 0.13378 0.01048 0.98932 0 11.93917 0.31745 10.47683 0.27854 1.59727 0.11764 1.40146 0.10320 57424.327867 0.000706 0.14917 0.01154 0.98770 0 12.54898 0.35057 10.99894 0.30724 1.87197 0.13505 1.63957 0.11830 57424.329212 0.000639 0.16744 0.01313 0.98643 0 12.39608 0.36703 10.77243 0.31899 2.07559 0.15073 1.80410 0.13106 57424.330488 0.000637 0.17828 0.01389 0.99545 0 11.65654 0.35532 10.17691 0.31017 2.07816 0.14896 1.81269 0.12991 57424.331813 0.000689 0.15930 0.01236 0.99160 0 12.15880 0.34847 10.62389 0.30448 1.93694 0.13959 1.69196 0.12195 57424.333260 0.000758 0.13492 0.01023 0.98473 0 13.20224 0.34486 11.46181 0.29940 1.78130 0.12681 1.54583 0.11004 57424.334944 0.000926 0.14694 0.01025 0.99063 0 12.11711 0.29931 10.59591 0.26171 1.78052 0.11620 1.55817 0.10169
