/* ** ** 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 58825.113625 0.000463 0.12129 0.00919 0.99375 0 22.32082 0.55589 20.68698 0.51513 2.70726 0.19362 2.50870 0.17942 58825.114566 0.000477 0.12344 0.00938 0.98788 0 21.20547 0.53190 19.72509 0.49476 2.61762 0.18769 2.43484 0.17459 58825.115865 0.000822 0.11000 0.00670 0.98754 0 21.80624 0.41162 20.28879 0.38298 2.39870 0.13886 2.23174 0.12920 58825.187755 0.000521 0.11681 0.00914 0.99444 0 20.09339 0.50020 18.54405 0.46162 2.34712 0.17403 2.16607 0.16062 58825.188770 0.000495 0.11955 0.00911 1.00000 0 21.32991 0.53238 19.43152 0.48492 2.54990 0.18359 2.32236 0.16715 58825.189795 0.000530 0.11112 0.00846 0.98907 0 21.45246 0.51457 19.75318 0.47384 2.38370 0.17228 2.19491 0.15863 58825.190761 0.000437 0.13381 0.01029 1.00000 0 21.41719 0.56735 19.53903 0.51753 2.86575 0.20683 2.61669 0.18882 58825.191690 0.000492 0.11879 0.00923 0.96471 0 21.71006 0.53513 19.98326 0.49256 2.57903 0.18997 2.37546 0.17494 58825.192668 0.000486 0.12599 0.00964 0.98214 0 20.64490 0.52730 19.00548 0.48544 2.60101 0.18768 2.39467 0.17280 58825.193608 0.000454 0.12799 0.00980 0.98089 0 21.79885 0.55679 20.06303 0.51247 2.79012 0.20132 2.56572 0.18514 58825.194470 0.000408 0.14466 0.01111 1.00000 0 21.17749 0.57970 19.56781 0.53564 3.06356 0.21992 2.83069 0.20321 58825.195683 0.000804 0.14181 0.00775 0.98921 0 21.70745 0.41940 19.95054 0.38543 3.07842 0.15730 2.82821 0.14452
