/* ** ** 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 55967.447286 0.000446 0.12452 0.01916 0.98701 0 13.17878 0.67934 5.40254 0.27159 1.64100 0.23791 0.65899 0.09320 55967.448038 0.000307 0.09310 0.02182 0.95283 0 13.77870 0.95299 4.22896 0.29230 1.28285 0.28720 0.39670 0.08870 55967.448747 0.000402 0.09229 0.01898 0.97842 0 13.72015 0.82510 4.22174 0.25388 1.26625 0.24907 0.39005 0.07673 55967.449736 0.000587 0.12611 0.01913 0.95074 0 13.24354 0.66733 4.07267 0.20521 1.67018 0.23900 0.51360 0.07350 55967.450865 0.000541 0.14016 0.02153 0.95187 0 12.89587 0.69111 3.95407 0.21190 1.80745 0.26016 0.55395 0.07974 55967.451990 0.000584 0.11859 0.01797 0.96040 0 14.06687 0.69952 4.30458 0.21404 1.66821 0.23871 0.51095 0.07312 55967.453107 0.000532 0.12391 0.01892 0.97826 0 14.34232 0.73030 4.41725 0.22491 1.77721 0.25584 0.54779 0.07886 55967.454259 0.000619 0.10761 0.01630 0.95794 0 14.68490 0.68122 4.51907 0.20963 1.58027 0.22784 0.48567 0.07002 55967.455231 0.000353 0.07733 0.01819 0.94262 0 14.52249 0.89850 4.44233 0.27483 1.12304 0.25486 0.34387 0.07804 55967.456229 0.000645 0.11113 0.01667 0.95964 0 13.72959 0.65212 4.19349 0.19918 1.52582 0.21705 0.46563 0.06624 55967.457830 0.000955 0.11047 0.01312 0.96061 0 15.01389 0.56231 4.57673 0.17141 1.65854 0.18701 0.50531 0.05697
