/* ** ** 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 55617.288397 0.000558 0.09460 0.01418 0.98446 0 6.31063 0.27666 5.52684 0.24231 0.59698 0.08556 0.52165 0.07476 55617.289563 0.000608 0.08456 0.01246 0.97619 0 6.59518 0.27296 5.77408 0.23899 0.55771 0.07887 0.48862 0.06910 55617.290709 0.000538 0.09569 0.01402 0.96237 0 6.82391 0.29306 5.97420 0.25656 0.65300 0.09144 0.57078 0.07993 55617.291710 0.000463 0.10843 0.01656 0.98750 0 6.55072 0.30978 5.72362 0.27067 0.71028 0.10317 0.62064 0.09015 55617.292708 0.000535 0.09175 0.01374 0.98919 0 6.73306 0.29214 5.89255 0.25568 0.61774 0.08853 0.54161 0.07762 55617.293700 0.000457 0.11415 0.01704 0.97468 0 6.48932 0.31083 5.69852 0.27295 0.74076 0.10476 0.65043 0.09199 55617.294736 0.000579 0.08412 0.01239 0.98500 0 6.88969 0.28450 6.04565 0.24965 0.57953 0.08196 0.50846 0.07191 55617.295845 0.000530 0.09182 0.01410 0.97814 0 6.72823 0.29332 5.90232 0.25732 0.61778 0.09096 0.54195 0.07979 55617.296689 0.000315 0.05862 0.01350 0.99083 0 7.21573 0.39715 6.32840 0.34831 0.42295 0.09457 0.37099 0.08296 55617.297508 0.000503 0.10000 0.01483 0.98851 0 6.64067 0.29707 5.82355 0.26051 0.66410 0.09392 0.58237 0.08236 55617.298617 0.000605 0.08333 0.01244 0.99522 0 6.52510 0.27218 5.71890 0.23855 0.54372 0.07792 0.47651 0.06829 55617.299687 0.000466 0.11053 0.01668 0.96273 0 6.59378 0.31183 5.79067 0.27385 0.72884 0.10446 0.63944 0.09164 55617.300761 0.000608 0.08782 0.01285 0.95714 0 6.66954 0.27401 5.84185 0.24001 0.58570 0.08227 0.51304 0.07206
