/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 55188.372774 0.001046 0.68230 0.19861 0.98611 1 0.19887 0.03706 0.16514 0.03078 0.13569 0.03034 0.11268 0.02520 55188.374764 0.000944 0.61499 0.17632 0.96923 1 0.24838 0.04420 0.20516 0.03651 0.15275 0.03434 0.12635 0.02840 55188.376187 0.000479 2.77326 1.21789 1.00000 1 0.10537 0.03983 0.08750 0.03307 0.29222 0.06534 0.24243 0.05421 55188.377843 0.001177 0.46284 0.12686 1.00000 1 0.25515 0.03957 0.21164 0.03282 0.11809 0.02669 0.09777 0.02210 55188.379761 0.000741 0.69660 0.20458 1.00000 1 0.27159 0.05133 0.22400 0.04233 0.18919 0.04253 0.15608 0.03508 55188.381475 0.000973 0.74825 0.22401 1.00000 1 0.19120 0.03780 0.15876 0.03139 0.14307 0.03216 0.11880 0.02671 55188.383697 0.001249 0.57188 0.16120 0.96512 1 0.20194 0.03434 0.16771 0.02852 0.11549 0.02596 0.09590 0.02156 55188.385876 0.000930 0.67959 0.19990 0.98438 1 0.22532 0.04275 0.18600 0.03528 0.15313 0.03442 0.12635 0.02840 55188.387561 0.000755 0.83495 0.25280 0.98077 1 0.22755 0.04645 0.18824 0.03842 0.18999 0.04249 0.15686 0.03508 55188.389972 0.001656 0.56661 0.12735 0.96989 1 0.23889 0.03228 0.19784 0.02673 0.13536 0.02431 0.11215 0.02014
