/* ** ** 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 56109.672861 0.000544 7.83713 1.73112 0.98936 0 0.31770 0.06640 0.27224 0.05687 2.48982 0.17801 2.13300 0.15250 56109.673885 0.000480 9.75996 2.41231 0.98795 0 0.28802 0.06813 0.24742 0.05853 2.81104 0.20154 2.41315 0.17301 56109.674898 0.000532 11.80979 3.03063 0.96196 0 0.22181 0.05468 0.19071 0.04701 2.61951 0.18681 2.25278 0.16066 56109.676009 0.000579 10.42708 2.64380 0.97000 0 0.22710 0.05521 0.19488 0.04738 2.36798 0.17048 2.03239 0.14632 56109.677123 0.000535 9.45802 2.27958 0.97297 0 0.26949 0.06196 0.23127 0.05317 2.54885 0.18431 2.18795 0.15821 56109.678159 0.000501 8.27645 1.86465 0.99422 0 0.32429 0.06927 0.27836 0.05946 2.68394 0.19216 2.30377 0.16494 56109.679169 0.000509 10.31932 2.54707 0.96023 0 0.26500 0.06260 0.22749 0.05374 2.73463 0.19552 2.34757 0.16784 56109.680205 0.000527 8.79930 2.02130 0.98901 0 0.29273 0.06388 0.24894 0.05432 2.57578 0.18468 2.19865 0.15763 56109.681215 0.000483 11.88927 3.19139 0.98802 0 0.23826 0.06167 0.20442 0.05292 2.83270 0.20123 2.43174 0.17274 56109.682178 0.000480 10.31639 2.51251 0.96988 0 0.28079 0.06537 0.23931 0.05571 2.89670 0.20711 2.46422 0.17618 56109.683350 0.000692 13.14837 3.12985 0.96653 0 0.20717 0.04763 0.17685 0.04066 2.72400 0.16789 2.32489 0.14328
