/* ** ** 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 59016.929061 0.000446 0.31046 0.01139 1.00000 0 46.03870 0.82061 41.56127 0.74081 14.29337 0.45840 12.90526 0.41388 59016.929958 0.000451 0.30747 0.01127 1.00000 0 46.40038 0.82509 41.57270 0.73918 14.26681 0.45717 12.78036 0.40952 59016.930878 0.000469 0.29823 0.01092 1.00000 0 45.81137 0.80255 41.07978 0.71964 13.66213 0.43905 12.25949 0.39391 59016.931798 0.000451 0.29984 0.01096 1.00000 0 47.00010 0.82497 42.47202 0.74544 14.09227 0.45165 12.73778 0.40823 59016.932707 0.000457 0.30112 0.01105 1.00000 0 46.73841 0.82771 41.73211 0.73902 14.07367 0.45217 12.56986 0.40388 59016.933639 0.000475 0.28667 0.01056 1.00000 0 46.73312 0.80695 41.75562 0.72094 13.39721 0.43611 11.98266 0.39008 59016.934567 0.000454 0.28508 0.01042 1.00000 0 48.83961 0.83850 44.10239 0.75714 13.92303 0.44941 12.57739 0.40594 59016.935485 0.000463 0.29935 0.01087 1.00000 0 46.07342 0.80561 41.78948 0.73070 13.79194 0.43870 12.50963 0.39791 59016.936428 0.000480 0.27965 0.01012 1.00000 0 47.53274 0.80559 42.95438 0.72801 13.29244 0.42486 12.01681 0.38407 59016.937366 0.000457 0.30428 0.01117 1.00000 0 45.49704 0.80696 41.26205 0.73185 13.84380 0.44474 12.55518 0.40334 59016.937944 0.000122 0.22373 0.01794 1.00000 0 47.41581 1.61252 42.92120 1.45964 10.60843 0.77049 9.59986 0.69724 59016.938537 0.000472 0.28594 0.01037 1.00000 0 47.28761 0.81072 42.66226 0.73139 13.52164 0.43195 12.19530 0.38956 59016.939469 0.000460 0.29112 0.01064 1.00000 0 47.42786 0.82426 42.80068 0.74375 13.80731 0.44407 12.45102 0.40041 59016.940404 0.000475 0.27749 0.01013 1.00000 0 47.95448 0.81248 43.32685 0.73405 13.30698 0.43048 12.01997 0.38888 59016.941341 0.000463 0.29011 0.01054 1.00000 0 47.75118 0.82483 42.81004 0.73945 13.85304 0.44254 12.42396 0.39687 59016.942409 0.000605 0.30124 0.00942 1.00000 0 47.98683 0.72248 42.99816 0.64732 14.45559 0.39604 12.94876 0.35472
