/* ** ** Swift/XRT hardness ratio for QSO B1727+502. ** 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 57137.129928 0.000959 0.29239 0.07437 1.00000 1 1.65537 0.20066 0.41553 0.05037 0.48401 0.10824 0.12121 0.02710 57137.131962 0.001075 0.24826 0.06098 0.98649 1 1.84754 0.20228 0.46176 0.05055 0.45867 0.10084 0.11427 0.02512 57137.133836 0.000799 0.33345 0.08653 1.00000 1 1.74435 0.22967 0.43664 0.05749 0.58165 0.13006 0.14546 0.03252 57137.135695 0.001060 0.23503 0.05854 0.98630 1 1.91346 0.20990 0.47395 0.05198 0.44972 0.10057 0.11111 0.02485 57137.137946 0.001191 0.28586 0.07374 0.98780 1 1.36863 0.16713 0.34209 0.04177 0.39124 0.08889 0.09733 0.02211 57137.140314 0.001177 0.19259 0.04751 0.97531 1 2.12829 0.21338 0.52381 0.05251 0.40988 0.09239 0.10053 0.02266 57137.142537 0.001046 0.26681 0.06731 0.97222 1 1.72358 0.20123 0.42730 0.04988 0.45987 0.10283 0.11429 0.02556 57137.144701 0.001118 0.30341 0.07368 0.95294 1 1.61320 0.18747 0.39568 0.04598 0.48947 0.10437 0.11993 0.02557 57137.195768 0.002135 0.28349 0.05812 0.96855 1 1.43442 0.13936 0.30522 0.02965 0.40664 0.07342 0.08670 0.01565
