/* ** ** 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 56324.935795 0.000506 10.19586 2.52144 0.98286 0 0.26803 0.06348 0.22700 0.05377 2.73277 0.19450 2.32258 0.16530 56324.936831 0.000530 9.19564 2.11008 0.97268 0 0.28635 0.06249 0.24459 0.05337 2.63313 0.18684 2.25026 0.15967 56324.937832 0.000472 12.06748 3.25260 0.97546 0 0.24032 0.06241 0.20524 0.05330 2.90002 0.20914 2.47648 0.17859 56324.938761 0.000457 9.62095 2.35451 0.98734 0 0.31107 0.07282 0.26533 0.06211 2.99276 0.21364 2.55398 0.18232 56324.939652 0.000434 10.43156 2.56894 0.99333 0 0.29937 0.07056 0.25574 0.06028 3.12288 0.22283 2.66765 0.19034 56324.940619 0.000532 12.15313 3.21608 0.97283 0 0.21460 0.05468 0.18327 0.04669 2.60811 0.18655 2.22810 0.15937 56324.941666 0.000515 9.09190 2.17118 0.99438 0 0.29092 0.06632 0.24832 0.05660 2.64504 0.18825 2.25697 0.16063 56324.942720 0.000538 10.53620 2.59470 0.97312 0 0.24429 0.05758 0.20844 0.04913 2.57384 0.18365 2.19602 0.15669 56324.943724 0.000466 9.56225 2.24535 0.97516 0 0.30894 0.06908 0.26360 0.05894 2.95419 0.21175 2.52157 0.18074 56324.944650 0.000460 9.53355 2.27020 0.97484 0 0.31285 0.07102 0.26713 0.06064 2.98253 0.21443 2.54725 0.18314 56324.945810 0.000700 7.42253 1.35972 0.98347 0 0.36262 0.06265 0.30976 0.05352 2.69152 0.16397 2.29864 0.14004
