/* ** ** 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 56003.150854 0.000903 6.85546 1.47640 0.95833 0 0.32180 0.06525 0.17985 0.03649 2.20611 0.16006 1.31931 0.09494 56003.152602 0.000845 9.49413 2.25951 0.98288 0 0.25847 0.05869 0.14648 0.03324 2.45398 0.17491 1.39044 0.09908 56003.154408 0.000961 7.52143 1.62031 0.95482 0 0.29441 0.05977 0.16462 0.03340 2.21437 0.15966 1.24277 0.08957 56003.156309 0.000935 5.81530 1.09651 0.95975 0 0.38817 0.06758 0.21675 0.03773 2.25730 0.16344 1.26584 0.09163 56003.158213 0.000969 6.36538 1.27266 0.97612 0 0.33126 0.06170 0.18692 0.03480 2.10859 0.15321 1.19984 0.08714 56003.160496 0.001314 7.66934 1.42979 0.96035 0 0.27761 0.04876 0.15618 0.02743 2.12906 0.13299 1.19987 0.07494
