/* ** ** Swift/XRT hardness ratio for Cen A. ** 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 54859.052192 0.000281 30.35022 12.57814 0.98969 0 0.15990 0.06528 0.13659 0.05576 4.85302 0.34540 4.16136 0.29616 54859.052794 0.000321 9.12475 2.12332 0.97297 0 0.47276 0.10467 0.40330 0.08928 4.31381 0.30891 3.67936 0.26344 54859.053440 0.000324 17.63567 5.61149 0.97321 0 0.23744 0.07358 0.20483 0.06348 4.18736 0.30196 3.61265 0.26051 54859.054050 0.000286 17.00222 5.26965 0.97980 0 0.27726 0.08360 0.23953 0.07222 4.71412 0.33840 4.07596 0.29259 54859.054635 0.000298 20.10437 6.84984 0.99029 0 0.22945 0.07648 0.19813 0.06604 4.61293 0.32535 3.98069 0.28076 54859.055260 0.000327 37.93956 17.18252 0.99115 0 0.10859 0.04856 0.09361 0.04187 4.11986 0.29454 3.55269 0.25399 54859.055856 0.000269 19.49829 6.32014 0.96774 0 0.26364 0.08337 0.22765 0.07199 5.14062 0.36586 4.43879 0.31591 54859.056431 0.000307 12.47520 3.34264 1.00000 0 0.34831 0.08993 0.30050 0.07759 4.34528 0.31112 3.74879 0.26841 54859.057059 0.000321 14.09284 4.12672 1.00000 0 0.29250 0.08303 0.25261 0.07171 4.12215 0.29635 3.55710 0.25573 54859.057693 0.000312 18.93010 6.13627 0.98148 0 0.22967 0.07263 0.19835 0.06272 4.34761 0.30974 3.75488 0.26751 54859.058344 0.000339 18.26830 5.92218 0.97436 0 0.22102 0.06989 0.19079 0.06033 4.03761 0.28809 3.48673 0.24878 54859.058998 0.000310 17.36870 5.52636 0.99065 0 0.24858 0.07705 0.21507 0.06665 4.31756 0.31054 3.73379 0.26855 54859.059626 0.000318 17.94229 5.86178 0.99091 0 0.23625 0.07531 0.20366 0.06492 4.23892 0.30364 3.65427 0.26176 54859.060236 0.000292 16.98417 5.26249 0.98020 0 0.27441 0.08274 0.23695 0.07144 4.66057 0.33269 4.02456 0.28729 54859.061162 0.000634 13.01984 2.57478 0.98174 0 0.31995 0.06112 0.27644 0.05281 4.16572 0.21323 3.59945 0.18424
