/* ** ** 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 54713.300122 0.001787 0.40549 0.10760 0.99187 1 0.20058 0.02866 0.16198 0.02314 0.08133 0.01819 0.06557 0.01466 54713.304422 0.002513 0.46095 0.09977 0.96926 1 0.19966 0.02411 0.16029 0.01936 0.09204 0.01653 0.07395 0.01328 54713.361883 0.001656 0.51309 0.14174 0.97368 1 0.17435 0.02800 0.14018 0.02251 0.08945 0.02011 0.07171 0.01612 54713.365529 0.001990 0.48838 0.13402 0.97810 1 0.15195 0.02392 0.12150 0.01912 0.07421 0.01668 0.05940 0.01335 54713.370903 0.003384 0.40716 0.07960 0.98060 1 0.19590 0.02072 0.15843 0.01676 0.07976 0.01311 0.06478 0.01065 54713.429866 0.002978 0.28104 0.07171 0.99024 1 0.21159 0.02552 0.13990 0.01687 0.05946 0.01337 0.03921 0.00881 54713.434703 0.001859 0.46413 0.12802 0.99219 1 0.20048 0.03170 0.13333 0.02108 0.09305 0.02103 0.06237 0.01409 54713.438770 0.002208 0.62335 0.13721 0.98999 1 0.21504 0.02966 0.14518 0.02002 0.13405 0.02299 0.09038 0.01550 54713.496942 0.002687 0.61355 0.17557 0.97297 1 0.20369 0.03623 0.07117 0.01264 0.12497 0.02801 0.04444 0.00994 54713.503623 0.003995 0.69131 0.17064 0.98002 1 0.16992 0.02687 0.05959 0.00942 0.11747 0.02226 0.04144 0.00785 54713.561538 0.001685 0.41604 0.11022 0.93966 1 0.21499 0.03054 0.17628 0.02504 0.08945 0.02000 0.07340 0.01641 54713.565562 0.002339 0.42990 0.09949 1.00000 1 0.19029 0.02445 0.15589 0.02003 0.08180 0.01574 0.06708 0.01291
