/* ** ** 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 56083.220879 0.000666 7.40120 1.61804 0.97826 0 0.27685 0.05721 0.23869 0.04927 2.04902 0.14624 1.76630 0.12606 56083.222140 0.000596 10.66472 2.74385 0.99029 0 0.21089 0.05210 0.18116 0.04474 2.24907 0.16153 1.93751 0.13913 56083.223301 0.000564 9.94514 2.42609 0.97436 0 0.24512 0.05716 0.21080 0.04915 2.43780 0.17461 2.09082 0.14976 56083.224383 0.000518 9.83338 2.44400 0.98324 0 0.26746 0.06367 0.22970 0.05469 2.62999 0.18781 2.26329 0.16161 56083.225482 0.000582 13.42489 3.79094 0.97512 0 0.17581 0.04803 0.15113 0.04129 2.36020 0.16844 2.02764 0.14471 56083.227279 0.001215 7.49664 1.19116 0.95814 0 0.30101 0.04526 0.25678 0.03860 2.25657 0.11597 1.93007 0.09919 56083.286013 0.000524 8.77292 2.10363 1.00000 0 0.28587 0.06535 0.24649 0.05638 2.50788 0.18142 2.16949 0.15694 56083.287086 0.000550 9.42943 2.27599 0.98421 0 0.26204 0.06039 0.22544 0.05197 2.47085 0.17720 2.12198 0.15218 56083.288258 0.000622 9.27841 2.21092 0.98140 0 0.23615 0.05362 0.20068 0.04556 2.19112 0.15829 1.86355 0.13460 56083.289456 0.000576 6.56747 1.31846 0.97990 0 0.36207 0.06794 0.31116 0.05839 2.37785 0.16976 2.04312 0.14586 56083.290622 0.000590 9.90843 2.38295 0.97549 0 0.23576 0.05409 0.20033 0.04596 2.33599 0.16847 1.97861 0.14270 56083.291785 0.000573 8.69255 2.00853 0.96970 0 0.29847 0.06583 0.25648 0.05658 2.59444 0.17877 2.22878 0.15357
