/* ** ** 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 55995.252700 0.000709 10.29675 2.53975 0.95918 0 0.21789 0.05137 0.15956 0.03761 2.24351 0.16246 1.67574 0.12121 55995.254068 0.000660 6.97386 1.43723 0.95614 0 0.35032 0.06762 0.25845 0.04989 2.44311 0.17637 1.80441 0.13027 55995.255530 0.000802 6.58572 1.32123 0.96751 0 0.30754 0.05770 0.22667 0.04252 2.02538 0.14391 1.49277 0.10607 55995.256965 0.000634 10.55566 2.73128 0.94521 0 0.24594 0.06107 0.17997 0.04472 2.59601 0.18870 1.89949 0.13806 55995.258371 0.000773 12.81988 3.64729 0.95880 0 0.16259 0.04473 0.11969 0.03292 2.08437 0.15093 1.53249 0.11097 55995.260304 0.001160 7.77570 1.34159 0.95761 0 0.28639 0.04664 0.21037 0.03427 2.22689 0.12690 1.63841 0.09337
