/* ** ** 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 55961.563763 0.000457 7.15960 2.57163 0.95570 0 0.27195 0.09212 0.11940 0.03980 1.94709 0.23260 0.97777 0.11516 55961.564605 0.000385 3.77843 1.07978 0.93985 0 0.58788 0.14975 0.25846 0.06582 2.22124 0.28772 0.97697 0.12647 55961.565389 0.000394 20.77202 15.09528 0.97059 0 0.09447 0.06729 0.03339 0.02361 1.96242 0.28334 0.74699 0.10753 55961.566170 0.000388 3.79823 1.73346 0.94030 0 0.32265 0.13175 0.10101 0.04124 1.22550 0.24979 0.39050 0.07957 55961.567128 0.000570 5.46561 1.99304 0.95939 0 0.31563 0.10595 0.10186 0.03395 1.72512 0.24580 0.52765 0.07497 55961.568048 0.000350 6.69319 2.70990 0.95041 0 0.30941 0.11698 0.12634 0.04775 2.07095 0.29995 0.85295 0.12351 55961.569003 0.000605 5.11045 1.85730 0.94737 0 0.26274 0.08765 0.10208 0.03365 1.34272 0.19366 0.50216 0.07160 55961.569943 0.000336 5.34871 2.93898 0.91379 0 0.24248 0.12128 0.07420 0.03710 1.29694 0.29508 0.37383 0.08457 55961.570823 0.000544 5.30252 1.92505 0.95213 0 0.34976 0.11673 0.10362 0.03454 1.85460 0.26501 0.55467 0.07918 55961.571951 0.000584 8.02071 3.46894 0.92079 0 0.22713 0.09280 0.06869 0.02804 1.82176 0.25841 0.53735 0.07617 55961.573060 0.000524 7.76981 3.48506 0.93370 0 0.23390 0.09934 0.06976 0.02962 1.81735 0.26225 0.58619 0.08387 55961.574515 0.000932 3.19688 0.68310 0.94410 0 0.47450 0.08841 0.19557 0.03641 1.51691 0.15867 0.61898 0.06475
