/* ** ** 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 56077.200969 0.000619 9.41588 2.21015 0.98598 0 0.23661 0.05291 0.20033 0.04480 2.22791 0.15897 1.88380 0.13441 56077.202221 0.000634 12.82026 3.54817 0.96804 0 0.17155 0.04585 0.14532 0.03884 2.19932 0.15812 1.86240 0.13390 56077.203370 0.000515 10.95086 2.81590 0.96629 0 0.24774 0.06116 0.20954 0.05173 2.71299 0.19505 2.29551 0.16504 56077.204470 0.000584 20.82151 7.33182 0.98020 0 0.11344 0.03911 0.09615 0.03315 2.36191 0.16904 2.00212 0.14329 56077.205705 0.000651 11.67443 3.03561 0.97333 0 0.18364 0.04591 0.15560 0.03890 2.14388 0.15327 1.81686 0.12989 56077.206929 0.000573 11.24264 2.89054 0.97475 0 0.21511 0.05311 0.18221 0.04498 2.41844 0.17361 2.04849 0.14705 56077.208142 0.000639 15.15955 4.64615 0.98643 0 0.14086 0.04195 0.11927 0.03552 2.13530 0.15428 1.80815 0.13065 56077.209374 0.000593 12.10802 3.24593 0.99024 0 0.18975 0.04899 0.16070 0.04149 2.29752 0.16568 1.93974 0.13988 56077.210885 0.000917 10.15847 2.04885 0.95899 0 0.22971 0.04436 0.19446 0.03755 2.33346 0.13580 1.97405 0.11488
