/* ** ** 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 59308.040825 0.000538 0.12418 0.01014 0.97312 0 18.26350 0.48733 16.78588 0.44795 2.26792 0.17500 2.08221 0.16072 59308.041861 0.000498 0.13219 0.01024 0.98837 0 19.27237 0.50535 17.50273 0.45888 2.54756 0.18575 2.31483 0.16880 59308.042850 0.000492 0.14019 0.01097 0.99412 0 18.31220 0.49687 16.52240 0.44835 2.56718 0.18848 2.31770 0.17014 59308.043909 0.000567 0.11721 0.00882 0.99490 0 19.25634 0.47190 17.44078 0.42741 2.25699 0.16068 2.04532 0.14559 59308.045070 0.000593 0.11457 0.00883 0.99512 0 18.44888 0.45154 16.76227 0.41027 2.11360 0.15456 1.91921 0.14032 59308.046207 0.000544 0.12898 0.00988 0.97340 0 18.47649 0.47670 16.76807 0.43250 2.38319 0.17196 2.15944 0.15578 59308.047309 0.000558 0.12465 0.00943 0.99482 0 18.38961 0.46538 16.75969 0.42405 2.29221 0.16342 2.08861 0.14891 59308.048481 0.000613 0.10653 0.00813 0.99057 0 19.39980 0.45346 17.57465 0.41080 2.06664 0.15008 1.87308 0.13603 59308.049641 0.000547 0.12520 0.00959 0.99471 0 18.55719 0.46996 16.89301 0.42777 2.32327 0.16788 2.11359 0.15270 59308.051134 0.000946 0.13050 0.00742 0.99694 0 18.52472 0.35673 16.89068 0.32523 2.41753 0.12923 2.20264 0.11775
