/* ** ** Swift/XRT hardness ratio for B2 1811+31. ** 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 59125.448183 0.002440 0.13084 0.03110 0.98810 1 0.46175 0.03725 0.36759 0.02965 0.06042 0.01351 0.04819 0.01078 59125.453369 0.002745 0.11410 0.02695 0.98413 1 0.46880 0.03567 0.37587 0.02859 0.05349 0.01196 0.04301 0.00962 59125.477699 0.021585 0.15093 0.03467 0.09923 1 0.50179 0.04157 0.39442 0.03268 0.07573 0.01623 0.05940 0.01273 59125.547045 0.025437 0.21127 0.04653 0.08449 1 0.62954 0.05719 0.33921 0.03019 0.13300 0.02669 0.06995 0.01379 59125.577173 0.004692 0.12289 0.02268 0.97765 1 0.71299 0.04370 0.34061 0.02087 0.08762 0.01525 0.04180 0.00728
