/* ** ** 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 56339.823665 0.000524 11.24016 2.84236 0.95580 0 0.25276 0.06131 0.20393 0.04946 2.84105 0.20311 2.30036 0.16442 56339.824764 0.000576 7.52386 1.63994 0.96482 0 0.33767 0.06951 0.27691 0.05700 2.54056 0.18209 2.08496 0.14943 56339.825809 0.000463 10.91330 2.80578 0.95000 0 0.28816 0.07112 0.23783 0.05870 3.14475 0.22637 2.59467 0.18677 56339.826764 0.000492 22.96830 8.91436 0.98235 0 0.12523 0.04775 0.10261 0.03914 2.87631 0.20796 2.35222 0.17008 56339.827785 0.000530 11.13061 2.86113 0.97814 0 0.24249 0.05986 0.19842 0.04897 2.69906 0.19350 2.21741 0.15897 56339.828867 0.000553 6.23676 1.26660 0.96859 0 0.41632 0.07911 0.34324 0.06522 2.59650 0.18607 2.14032 0.15338 56339.829993 0.000573 6.22749 1.21424 0.96970 0 0.40251 0.07299 0.33108 0.06003 2.50660 0.17963 2.06229 0.14779 56339.831113 0.000547 7.48166 1.61001 0.98413 0 0.34846 0.07075 0.28541 0.05794 2.60707 0.18599 2.13725 0.15248 56339.832149 0.000489 13.90281 4.00269 0.96450 0 0.21382 0.05964 0.17533 0.04891 2.97264 0.21208 2.43883 0.17399 56339.833147 0.000509 8.17280 1.80119 0.96023 0 0.35009 0.07300 0.28798 0.06005 2.86122 0.20413 2.35224 0.16781 56339.834163 0.000506 14.71478 4.30642 0.96571 0 0.19357 0.05493 0.15950 0.04526 2.84831 0.20381 2.34605 0.16787 56339.835196 0.000527 10.56313 2.64141 0.94505 0 0.26756 0.06413 0.21936 0.05256 2.82626 0.20142 2.31982 0.16532 56339.836257 0.000535 12.07322 3.14727 0.97838 0 0.23471 0.05896 0.19304 0.04850 2.83374 0.19724 2.33102 0.16225
