/* ** ** 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 56089.770702 0.000489 20.41758 6.96294 0.97633 0 0.13694 0.04565 0.11784 0.03928 2.79605 0.20134 2.38958 0.17207 56089.771625 0.000434 11.34613 3.00438 0.99333 0 0.27033 0.06888 0.23349 0.05949 3.06717 0.22119 2.64261 0.19058 56089.772649 0.000590 12.03101 3.12786 0.98529 0 0.19038 0.04760 0.16438 0.04109 2.29048 0.16343 1.97748 0.14110 56089.773758 0.000518 11.64732 3.08414 0.96089 0 0.23040 0.05872 0.19701 0.05019 2.68349 0.19267 2.29852 0.16501 56089.774701 0.000425 12.04750 3.14836 0.95918 0 0.27105 0.06814 0.23399 0.05882 3.26552 0.23301 2.81896 0.20114 56089.775604 0.000477 12.28897 3.35558 0.98788 0 0.22949 0.06046 0.19811 0.05220 2.82020 0.20225 2.43446 0.17458 56089.776651 0.000570 20.80783 7.09450 0.96954 0 0.11538 0.03846 0.09961 0.03320 2.40088 0.17209 2.07266 0.14857 56089.777768 0.000547 8.19164 1.82767 0.97354 0 0.30498 0.06443 0.26326 0.05562 2.49828 0.17916 2.15661 0.15466 56089.778775 0.000460 11.71700 3.04728 0.98113 0 0.25093 0.06273 0.21658 0.05414 2.94015 0.21075 2.53768 0.18190 56089.779765 0.000530 8.54362 1.97161 0.98361 0 0.29703 0.06509 0.25449 0.05578 2.53770 0.18357 2.18158 0.15781 56089.780832 0.000538 10.87569 2.79671 0.98387 0 0.22987 0.05676 0.19837 0.04898 2.50003 0.17975 2.15745 0.15512 56089.782351 0.000981 9.53414 1.64613 0.98230 0 0.28059 0.04625 0.24214 0.03991 2.67514 0.13751 2.30865 0.11867
