/* ** ** 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 55680.125685 0.000608 0.11819 0.01799 0.95714 0 5.58620 0.27351 4.15814 0.20351 0.66022 0.09516 0.49057 0.07062 55680.126937 0.000645 0.11070 0.01754 0.90583 0 5.83192 0.27771 4.22277 0.20108 0.64561 0.09757 0.46751 0.07065 55680.128216 0.000634 0.11539 0.01760 0.89954 0 5.98560 0.28519 4.31556 0.20560 0.69066 0.10007 0.49788 0.07210 55680.129174 0.000324 0.09480 0.02226 0.94643 0 5.60401 0.38553 4.08415 0.28097 0.53125 0.11927 0.38706 0.08689 55680.130100 0.000602 0.11640 0.01757 0.92308 0 6.14324 0.29409 4.43026 0.21206 0.71510 0.10234 0.51628 0.07388 55680.131081 0.000379 0.08226 0.01936 0.90076 0 5.61691 0.35065 4.07146 0.25418 0.46205 0.10485 0.33513 0.07605 55680.131810 0.000350 0.08279 0.01983 0.97521 0 5.52300 0.36184 3.98781 0.26124 0.45725 0.10535 0.33072 0.07618 55680.132777 0.000616 0.10673 0.01632 0.95305 0 6.20882 0.28744 4.49994 0.20833 0.66269 0.09655 0.48060 0.07002 55680.134027 0.000634 0.10697 0.01629 0.97717 0 5.91557 0.27823 4.28397 0.20149 0.63279 0.09164 0.45833 0.06637 55680.135100 0.000440 0.05956 0.01371 0.98684 0 6.18743 0.33958 4.48587 0.24620 0.36853 0.08241 0.26711 0.05973 55680.136174 0.000634 0.10404 0.01659 0.96347 0 5.51402 0.26910 3.99027 0.19473 0.57365 0.08706 0.41529 0.06303
