/* ** ** 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 59703.556140 0.000807 0.12305 0.00962 0.98925 0 12.38587 0.31587 11.43808 0.29168 1.52412 0.11257 1.40657 0.10388 59703.557752 0.000804 0.12814 0.00964 0.98921 0 12.24356 0.31329 11.37011 0.29093 1.56887 0.11094 1.45697 0.10302 59703.559387 0.000830 0.12069 0.00929 0.99652 0 12.23236 0.30989 11.38212 0.28835 1.47631 0.10726 1.37372 0.09981 59703.561086 0.000868 0.11204 0.00849 0.99000 0 12.80441 0.30821 11.89316 0.28627 1.43464 0.10311 1.33332 0.09582 59703.562686 0.000732 0.14328 0.01090 0.98024 0 12.07063 0.32595 11.23226 0.30331 1.72943 0.12295 1.60932 0.11441 59703.564694 0.001276 0.11014 0.00704 0.99093 0 12.59446 0.25425 11.71939 0.23658 1.38714 0.08407 1.29075 0.07823
