/* ** ** 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 55965.641425 0.000758 14.38700 4.14372 0.95802 0 0.13139 0.03668 0.11065 0.03087 1.89027 0.13413 1.59591 0.11323 55965.642904 0.000720 9.39087 2.24119 0.96787 0 0.20801 0.04739 0.17607 0.04011 1.95337 0.13895 1.65382 0.11764 55965.644400 0.000775 8.76181 2.02539 0.97015 0 0.20642 0.04537 0.17452 0.03835 1.80865 0.12943 1.52489 0.10912 55965.645951 0.000775 13.15577 3.73131 0.96642 0 0.13848 0.03802 0.11719 0.03215 1.82178 0.12983 1.54054 0.10979 55965.647464 0.000738 10.91686 2.80774 0.96863 0 0.17203 0.04246 0.14579 0.03599 1.87808 0.13581 1.59029 0.11500 55965.648931 0.000729 7.34068 1.56621 0.94841 0 0.26520 0.05323 0.22385 0.04492 1.94676 0.14078 1.64352 0.11885 55965.651202 0.001542 10.40524 1.84061 0.96623 0 0.17529 0.02970 0.14745 0.02499 1.82391 0.09253 1.53192 0.07771
