/* ** ** 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 57840.002760 0.000436 0.14347 0.03210 0.99892 1 10.24298 0.83129 2.13937 0.17362 1.46952 0.30642 0.30696 0.06401 57840.004989 0.001279 0.14039 0.00795 0.99009 0 13.06911 0.25898 11.85147 0.23485 1.83478 0.09738 1.66383 0.08831 57840.246709 0.000631 0.15161 0.01210 0.98624 0 13.46106 0.38096 11.84165 0.33513 2.04080 0.15229 1.79529 0.13397 57840.247971 0.000631 0.15349 0.01193 0.98624 0 13.61759 0.38286 11.97935 0.33680 2.09020 0.15142 1.83874 0.13320 57840.249256 0.000654 0.14597 0.01120 0.99115 0 13.80203 0.37916 12.14160 0.33355 2.01468 0.14438 1.77231 0.12701 57840.250624 0.000715 0.14510 0.01113 0.97571 0 12.90494 0.35338 11.35243 0.31087 1.87257 0.13419 1.64729 0.11805 57840.251970 0.000631 0.15153 0.01166 0.99541 0 13.72430 0.38482 12.07322 0.33853 2.07967 0.14904 1.82948 0.13111 57840.253214 0.000613 0.15742 0.01223 0.99057 0 13.58853 0.39245 11.95378 0.34524 2.13906 0.15432 1.88172 0.13576 57840.254493 0.000666 0.15152 0.01164 0.97391 0 13.29684 0.36802 11.69719 0.32374 2.01468 0.14438 1.77231 0.12701 57840.256403 0.001238 0.14077 0.00809 0.99065 0 13.56423 0.27332 11.93241 0.24044 1.90941 0.10276 1.67970 0.09040
