/* ** ** 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 56001.139310 0.000567 8.26508 1.82308 0.96939 0 0.29669 0.06187 0.25042 0.05222 2.45214 0.17632 2.07781 0.14940 56001.140404 0.000527 17.34470 5.37541 0.97802 0 0.15086 0.04549 0.12812 0.03863 2.61662 0.18758 2.22389 0.15942 56001.141431 0.000501 11.50277 3.04467 0.98266 0 0.23919 0.06095 0.20334 0.05181 2.75140 0.19703 2.33718 0.16737 56001.142537 0.000605 14.66168 4.29439 0.99043 0 0.15311 0.04347 0.13015 0.03695 2.24488 0.16142 1.90716 0.13713 56001.143677 0.000535 12.23264 3.23732 0.96216 0 0.21584 0.05499 0.18325 0.04669 2.64025 0.18887 2.24039 0.16027 56001.144713 0.000501 12.00838 3.17852 0.97688 0 0.23040 0.05871 0.19577 0.04988 2.76668 0.19813 2.35101 0.16836 56001.145731 0.000512 11.61932 3.02131 0.97740 0 0.23287 0.05822 0.19786 0.04947 2.70578 0.19347 2.29975 0.16444 56001.146851 0.000608 7.84682 1.73637 0.96667 0 0.29269 0.06129 0.24873 0.05208 2.29671 0.16439 1.95265 0.13976 56001.148072 0.000613 11.37678 2.87542 0.98113 0 0.19943 0.04837 0.16944 0.04109 2.26888 0.16133 1.92755 0.13706 56001.149669 0.000984 14.71337 3.13949 0.96765 0 0.18003 0.03723 0.15239 0.03150 2.64880 0.13918 2.24199 0.11780
