/* ** ** 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 59376.211145 0.000477 0.16617 0.01324 0.98182 0 19.36793 0.57435 14.93535 0.43726 3.21831 0.23804 2.41649 0.17672 59376.212198 0.000576 0.14015 0.01078 0.95477 0 18.22381 0.48445 14.81635 0.39387 2.55407 0.18429 2.07974 0.15005 59376.213289 0.000515 0.13926 0.01075 0.98876 0 20.08945 0.54190 16.18087 0.43630 2.79759 0.20237 2.25748 0.16312 59376.214342 0.000538 0.14443 0.01115 0.98387 0 18.37273 0.50501 14.97486 0.41157 2.65365 0.19142 2.15929 0.15579 59376.215430 0.000550 0.13708 0.01069 0.98947 0 18.78084 0.50676 15.20128 0.41010 2.57446 0.18832 2.08229 0.15228 59376.216541 0.000561 0.13098 0.01019 0.99485 0 19.11808 0.50697 15.48029 0.41044 2.50412 0.18314 2.02835 0.14833 59376.217609 0.000506 0.14462 0.01127 0.98286 0 19.48417 0.53489 15.87766 0.43589 2.81783 0.20547 2.28764 0.16685 59376.218616 0.000501 0.14922 0.01195 0.98266 0 18.80815 0.52926 15.24879 0.42902 2.80660 0.21033 2.27128 0.17019 59376.219767 0.000651 0.11550 0.00886 0.98667 0 19.00474 0.46597 15.32352 0.37567 2.19509 0.15950 1.77167 0.12869 59376.220971 0.000553 0.15940 0.01180 0.98953 0 18.00386 0.49701 14.46481 0.39921 2.86983 0.19708 2.30273 0.15812
