/* ** ** 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 59252.224157 0.000460 0.14859 0.02294 0.96226 0 13.89574 0.76176 4.34990 0.23781 2.06474 0.29795 0.64460 0.09277 59252.224999 0.000382 0.21081 0.03334 0.94697 0 12.32178 0.80820 3.74614 0.24570 2.59750 0.37383 0.78899 0.11355 59252.225933 0.000553 0.15253 0.02283 0.95812 0 12.22094 0.66404 3.71296 0.20175 1.86402 0.25995 0.56644 0.07899 59252.226937 0.000451 0.17343 0.02688 0.95513 0 12.63974 0.75352 3.83591 0.22868 2.19210 0.31364 0.66536 0.09520 59252.227834 0.000446 0.17208 0.02695 0.94805 0 12.88842 0.77077 3.90933 0.23380 2.21785 0.32107 0.67199 0.09728 59252.228720 0.000440 0.18156 0.02808 0.93421 0 12.82311 0.77224 3.90138 0.23496 2.32816 0.33167 0.70864 0.10095 59252.229530 0.000370 0.23435 0.03684 0.98438 0 11.35793 0.79387 3.44235 0.24060 2.66177 0.37484 0.80679 0.11362 59252.230340 0.000440 0.20111 0.03162 0.96711 0 11.04301 0.71955 3.35568 0.21865 2.22091 0.31775 0.67441 0.09649 59252.231171 0.000391 0.22809 0.03620 0.96296 0 11.00756 0.75553 3.34385 0.22952 2.51068 0.35924 0.76260 0.10911 59252.232047 0.000486 0.16768 0.02610 0.95833 0 12.00110 0.71154 3.65275 0.21656 2.01236 0.28961 0.61257 0.08816 59252.232918 0.000385 0.21119 0.03373 0.96241 0 11.96144 0.80639 3.63181 0.24484 2.52609 0.36570 0.76648 0.11096 59252.233645 0.000341 0.10596 0.02232 0.98305 0 13.42319 0.88709 4.06602 0.26870 1.42235 0.28447 0.43175 0.08635
