/* ** ** 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 56371.466120 0.000472 8.54978 1.93019 0.96319 0 0.34383 0.07368 0.29790 0.06383 2.93968 0.20896 2.54736 0.18107 56371.467049 0.000457 11.34294 2.86750 0.98734 0 0.25984 0.06302 0.22554 0.05470 2.94738 0.21016 2.55668 0.18230 56371.467931 0.000425 8.90039 1.99865 0.97279 0 0.36815 0.07849 0.31707 0.06760 3.27669 0.23091 2.82606 0.19915 56371.468817 0.000460 7.32642 1.54531 0.98742 0 0.39928 0.07925 0.34590 0.06866 2.92528 0.20881 2.53112 0.18066 56371.469725 0.000448 8.24524 1.86472 0.95484 0 0.37195 0.07969 0.32131 0.06885 3.06679 0.22202 2.65178 0.19196 56371.470640 0.000466 11.32754 2.92853 0.96273 0 0.26093 0.06484 0.22644 0.05626 2.95567 0.21096 2.56378 0.18299 56371.471528 0.000422 8.67320 2.00759 0.98630 0 0.37136 0.08182 0.32271 0.07110 3.22086 0.22850 2.79756 0.19847 56371.472321 0.000370 11.83106 3.07478 0.99219 0 0.30769 0.07692 0.26711 0.06678 3.64032 0.25851 3.16057 0.22444 56371.473131 0.000440 7.51009 1.65047 0.99342 0 0.40177 0.08345 0.34851 0.07238 3.01734 0.21671 2.61720 0.18797 56371.473985 0.000414 20.07115 7.13646 1.00000 0 0.15819 0.05508 0.13726 0.04780 3.17508 0.22876 2.75597 0.19856 56371.474858 0.000460 10.11086 2.47693 0.94969 0 0.30092 0.07055 0.26140 0.06129 3.04258 0.21615 2.64256 0.18773 56371.475715 0.000396 7.78243 1.72952 0.99270 0 0.43472 0.09147 0.37713 0.07934 3.38317 0.24200 2.92462 0.20919 56371.476924 0.000813 8.53840 1.38985 0.97509 0 0.37780 0.05832 0.32618 0.05035 3.22583 0.16670 2.79293 0.14432
