/* ** ** 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 56417.174635 0.000972 0.43069 0.11746 0.96131 0 0.42991 0.06522 0.28767 0.04289 0.18516 0.04196 0.12405 0.02774 56417.176281 0.000674 1.10067 0.36041 0.97854 0 0.23635 0.05652 0.16027 0.03832 0.26014 0.05819 0.17573 0.03929 56417.177852 0.000897 0.39452 0.10477 0.98710 0 0.48655 0.06969 0.33194 0.04754 0.19195 0.04292 0.13094 0.02928 56417.179429 0.000680 0.46243 0.12722 0.97021 0 0.54928 0.08579 0.37505 0.05857 0.25401 0.05753 0.17362 0.03932 56417.180830 0.000720 0.65310 0.18959 0.98795 0 0.36450 0.06683 0.24941 0.04573 0.23805 0.05358 0.16189 0.03643 56417.182378 0.000828 0.45905 0.12486 0.96503 0 0.46620 0.07216 0.31694 0.04906 0.21401 0.04786 0.14517 0.03246 56417.184215 0.001010 0.63905 0.14178 0.97708 0 0.45488 0.06402 0.31225 0.04395 0.29069 0.04985 0.19975 0.03426
