/* ** ** 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 56000.333707 0.000480 0.15796 0.01230 1.00000 0 17.26294 0.49274 15.09884 0.43073 2.72688 0.19749 2.38160 0.17251 56000.334676 0.000489 0.14607 0.01121 1.00000 0 18.50586 0.50887 16.07782 0.44210 2.70320 0.19373 2.34914 0.16834 56000.335631 0.000466 0.16751 0.01306 0.99379 0 17.03067 0.50392 14.74710 0.43636 2.85276 0.20581 2.46983 0.17818 56000.336583 0.000486 0.15789 0.01219 1.00000 0 17.38269 0.49559 15.04544 0.42896 2.74455 0.19698 2.37607 0.17053 56000.337579 0.000509 0.15178 0.01174 0.98864 0 17.24625 0.48085 14.96241 0.41718 2.61772 0.18884 2.27111 0.16384 56000.338664 0.000576 0.12393 0.00951 0.99497 0 18.59827 0.47063 16.11316 0.40774 2.30484 0.16695 1.99669 0.14463 56000.339737 0.000498 0.15351 0.01169 1.00000 0 17.60062 0.49323 15.25886 0.42761 2.70190 0.19136 2.34211 0.16588 56000.340724 0.000489 0.15118 0.01176 0.98225 0 18.12931 0.50568 15.67444 0.43720 2.74079 0.19906 2.36953 0.17209 56000.341719 0.000506 0.14914 0.01126 0.99429 0 18.00757 0.49255 15.58755 0.42636 2.68569 0.18897 2.32571 0.16364 56000.342729 0.000503 0.15143 0.01169 0.98276 0 17.77826 0.49233 15.41728 0.42695 2.69214 0.19401 2.33539 0.16829 56000.344187 0.000949 0.15660 0.00886 0.97561 0 17.56048 0.35782 15.19626 0.30965 2.74999 0.14521 2.37969 0.12566
