/* ** ** 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 56380.751507 0.000579 12.17810 3.28158 0.96000 0 0.20068 0.05211 0.16941 0.04398 2.44387 0.17578 2.06164 0.14826 56380.752566 0.000480 15.14132 4.53089 0.98795 0 0.18895 0.05490 0.16020 0.04655 2.86093 0.20460 2.43226 0.17394 56380.753463 0.000417 11.46908 3.04845 0.96528 0 0.28951 0.07407 0.24793 0.06344 3.32042 0.23914 2.84396 0.20482 56380.754352 0.000472 11.90299 3.25137 0.98773 0 0.24211 0.06381 0.20646 0.05438 2.88183 0.20684 2.45596 0.17627 56380.755301 0.000477 12.36054 3.32637 0.98182 0 0.23355 0.06063 0.20001 0.05192 2.88686 0.20483 2.47264 0.17544 56380.756218 0.000440 8.22031 1.83536 0.98684 0 0.37181 0.07854 0.31854 0.06729 3.05639 0.22103 2.61854 0.18936 56380.757115 0.000457 15.63650 4.76407 0.98734 0 0.19270 0.05706 0.16217 0.04800 3.01318 0.21625 2.53468 0.18192 56380.758021 0.000448 10.05900 2.48885 0.99355 0 0.29794 0.07055 0.25525 0.06044 2.99697 0.21510 2.56760 0.18429 56380.758897 0.000428 15.46121 4.82276 0.97973 0 0.20639 0.06266 0.17683 0.05369 3.19103 0.22835 2.73421 0.19566 56380.759832 0.000506 13.19980 3.74280 0.98857 0 0.20265 0.05560 0.17361 0.04764 2.67493 0.19142 2.29168 0.16399 56380.760859 0.000521 7.71314 1.67837 0.97222 0 0.34319 0.07051 0.29402 0.06041 2.64707 0.18979 2.26793 0.16260 56380.762283 0.000903 15.13751 3.34919 0.96474 0 0.18305 0.03929 0.15638 0.03357 2.77085 0.14861 2.35934 0.12653
