/* ** ** 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 59138.856470 0.001438 0.25964 0.06519 0.98990 1 0.40945 0.04673 0.31386 0.03582 0.10631 0.02377 0.08163 0.01825 59138.859317 0.001409 0.21301 0.05258 0.98969 1 0.51192 0.05350 0.39061 0.04082 0.10904 0.02438 0.08333 0.01863 59138.863689 0.002963 0.10227 0.02343 0.97338 1 0.53856 0.03764 0.41372 0.02892 0.05508 0.01202 0.04230 0.00923 59138.924814 0.001191 0.27762 0.07033 1.00000 1 0.43516 0.05181 0.35397 0.04214 0.12081 0.02702 0.09756 0.02182 59138.927254 0.001249 0.25827 0.06543 0.97674 1 0.45076 0.05152 0.36568 0.04179 0.11642 0.02632 0.09425 0.02131 59138.930900 0.002397 0.18165 0.03390 0.98725 1 0.56361 0.04146 0.45937 0.03379 0.10238 0.01756 0.08349 0.01432
