/* ** ** 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 56187.122061 0.000868 6.73778 1.36556 0.97667 0 0.23619 0.04483 0.20139 0.03822 1.59141 0.11307 1.36182 0.09675 56187.123852 0.000923 4.00079 0.66445 0.96238 0 0.37269 0.05585 0.32263 0.04835 1.49106 0.10677 1.29073 0.09242 56187.125712 0.000938 5.04812 0.90070 0.97531 0 0.28800 0.04711 0.24942 0.04080 1.45385 0.10361 1.25920 0.08974 56187.127474 0.000825 7.16985 1.53423 0.96491 0 0.23436 0.04729 0.20188 0.04073 1.68033 0.11976 1.44694 0.10312 56187.129277 0.000978 7.30468 1.55345 0.98521 0 0.18654 0.03731 0.16156 0.03231 1.36260 0.09851 1.18001 0.08530 56187.131450 0.001195 5.76807 0.88518 0.97579 0 0.30239 0.04297 0.26145 0.03715 1.74418 0.10113 1.50781 0.08742
