/* ** ** Swift/XRT hardness ratio for QSO B1727+502. ** 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 58309.310130 0.000880 0.27200 0.06955 0.96053 0 0.69608 0.08264 0.49585 0.05884 0.18933 0.04288 0.13561 0.03070 58309.312807 0.001797 0.19214 0.03738 0.96688 0 0.76532 0.06097 0.55288 0.04405 0.14705 0.02610 0.10638 0.01888 58309.373153 0.001322 0.14669 0.03552 0.97374 0 0.82126 0.07336 0.61132 0.05461 0.12047 0.02711 0.08951 0.02014 58309.375364 0.000888 0.20505 0.05045 0.96091 0 0.90314 0.09267 0.66685 0.06841 0.18519 0.04142 0.13582 0.03037 58309.377711 0.001458 0.22197 0.04305 0.97024 0 0.82985 0.06975 0.61108 0.05136 0.18421 0.03220 0.13472 0.02354
