/* ** ** 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 56063.164059 0.000723 9.22598 2.25689 0.97200 0 0.21286 0.04979 0.17742 0.04150 1.96384 0.14059 1.63560 0.11708 56063.165477 0.000694 10.68192 2.70100 0.97083 0 0.19245 0.04668 0.15914 0.03860 2.05575 0.14690 1.70392 0.12174 56063.166932 0.000761 11.92867 3.15690 0.96958 0 0.15573 0.03966 0.12976 0.03305 1.85763 0.13371 1.54668 0.11133 56063.168396 0.000697 8.04747 1.77983 0.95851 0 0.25684 0.05374 0.21380 0.04474 2.06694 0.14819 1.71830 0.12318 56063.169829 0.000735 10.48883 2.66301 0.96850 0 0.18616 0.04535 0.15358 0.03742 1.95260 0.13952 1.61387 0.11531 56063.171400 0.000836 9.11305 2.05098 0.97634 0 0.21572 0.04640 0.18047 0.03881 1.96590 0.13032 1.64103 0.10878 56063.234999 0.000715 10.85627 2.75874 0.95547 0 0.18551 0.04524 0.15479 0.03776 2.01391 0.14372 1.68405 0.12018 56063.237276 0.001562 13.29263 2.71328 0.97778 0 0.13185 0.02605 0.11053 0.02183 1.75267 0.08987 1.46971 0.07536
