/* ** ** 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 59409.431986 0.001162 0.30992 0.07980 0.96250 1 0.41338 0.05105 0.33317 0.04114 0.12811 0.02895 0.10286 0.02324 59409.433802 0.000654 0.67832 0.20044 1.00000 1 0.32083 0.06109 0.25861 0.04924 0.21762 0.04918 0.17601 0.03977 59409.435225 0.000770 0.41658 0.11257 1.00000 1 0.44489 0.06590 0.35922 0.05321 0.18533 0.04189 0.14944 0.03377 59409.437085 0.001089 0.33265 0.07814 0.98304 1 0.50001 0.06021 0.40451 0.04871 0.16633 0.03355 0.13455 0.02714 59409.833069 0.000741 0.50342 0.13846 0.98039 1 0.40074 0.06417 0.31837 0.05098 0.20174 0.04511 0.16000 0.03578 59409.835640 0.001830 0.34047 0.06497 0.98620 1 0.44044 0.04267 0.35017 0.03392 0.14996 0.02465 0.11910 0.01958
