/* ** ** 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 56442.140393 0.000451 0.69706 0.20184 0.95513 0 0.53214 0.09884 0.39522 0.07339 0.37093 0.08239 0.27765 0.06167 56442.141241 0.000396 0.87161 0.26784 0.96350 0 0.46320 0.09763 0.34817 0.07338 0.40373 0.09028 0.30354 0.06787 56442.142239 0.000602 0.54116 0.15190 0.97115 0 0.48366 0.08117 0.36372 0.06104 0.26174 0.05889 0.19719 0.04437 56442.143316 0.000475 0.73528 0.21692 0.96341 0 0.45621 0.08780 0.34452 0.06630 0.33544 0.07501 0.25359 0.05670 56442.144470 0.000680 0.43194 0.11810 0.96596 0 0.53079 0.08024 0.40143 0.06069 0.22927 0.05223 0.17342 0.03951 56442.145795 0.000645 0.55437 0.15557 0.97758 0 0.43841 0.07434 0.33156 0.05622 0.24304 0.05435 0.18379 0.04110 56442.147048 0.000608 0.58299 0.16713 0.95238 0 0.44640 0.07768 0.33759 0.05875 0.26025 0.05929 0.19683 0.04484 56442.148191 0.000535 0.69278 0.20358 0.98919 0 0.41792 0.07968 0.31606 0.06026 0.28953 0.06474 0.21894 0.04896 56442.149120 0.000394 0.60932 0.17267 0.94853 0 0.67874 0.11816 0.51248 0.08921 0.41357 0.09248 0.31059 0.06945 56442.150457 0.000938 0.56707 0.13271 0.99074 0 0.42204 0.06011 0.31916 0.04546 0.23932 0.04444 0.18099 0.03361
