/* ** ** 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 57195.468480 0.000119 0.25235 0.09996 0.98937 0 1.91146 0.34146 1.56597 0.27974 0.48235 0.17054 0.39509 0.13969 57195.530732 0.000339 0.28098 0.06898 0.99145 0 1.63349 0.18834 1.36333 0.15716 0.45898 0.09948 0.38374 0.08319 57195.531418 0.000347 0.22077 0.05618 0.96667 0 1.79208 0.19379 1.52321 0.16472 0.39563 0.09114 0.33642 0.07749 57195.532156 0.000391 0.21547 0.05559 0.99259 0 1.56497 0.17050 1.33377 0.14531 0.33720 0.07885 0.28734 0.06720 57195.532876 0.000330 0.24405 0.06093 0.95614 0 1.77047 0.19661 1.50613 0.16725 0.43209 0.09662 0.36758 0.08219 57195.533597 0.000391 0.20462 0.05021 0.95556 0 1.78387 0.18036 1.51759 0.15343 0.36501 0.08162 0.31059 0.06945 57195.534477 0.000489 0.27557 0.05477 0.96996 0 1.70505 0.15865 1.45228 0.13513 0.46986 0.08253 0.40012 0.07028
