/* ** ** 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 56009.493745 0.000599 7.19164 1.54364 0.99517 0 0.31632 0.06400 0.26650 0.05392 2.27488 0.16298 1.92248 0.13774 56009.494922 0.000579 9.43067 2.24513 0.99000 0 0.25299 0.05742 0.21151 0.04799 2.38585 0.17143 1.99495 0.14335 56009.496085 0.000584 10.51217 2.59791 0.97525 0 0.22742 0.05381 0.19188 0.04540 2.39069 0.17054 2.01815 0.14396 56009.497280 0.000611 13.93489 3.99096 0.96682 0 0.16762 0.04649 0.14002 0.03883 2.33576 0.16668 1.95367 0.13941 56009.498423 0.000532 11.21222 2.87876 0.98370 0 0.23511 0.05800 0.19730 0.04868 2.63611 0.18756 2.20762 0.15707 56009.499456 0.000501 17.51699 5.57297 0.97688 0 0.15941 0.04940 0.13451 0.04165 2.79230 0.20098 2.33424 0.16797 56009.500481 0.000524 12.12428 3.26217 0.97790 0 0.22150 0.05744 0.18466 0.04790 2.68548 0.19240 2.23746 0.16030 56009.501595 0.000590 12.58468 3.37233 0.98039 0 0.18709 0.04831 0.15733 0.04062 2.35442 0.16869 1.98016 0.14187 56009.503157 0.000972 11.75662 2.21618 0.98512 0 0.23678 0.04293 0.19740 0.03579 2.78375 0.14358 2.31564 0.11943
