/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** 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 59769.101875 0.000136 0.22327 0.06108 0.95026 0 4.00032 0.46301 3.45779 0.40021 0.89316 0.22141 0.77202 0.19138 59769.102639 0.000610 0.30258 0.07773 0.97619 1 2.58173 0.31831 0.63790 0.07862 0.78117 0.17606 0.19370 0.04365 59769.103583 0.000334 0.41966 0.11431 1.00000 1 3.40378 0.52064 0.82698 0.12647 1.42841 0.32195 0.34529 0.07782 59769.104425 0.000508 0.35627 0.09318 0.97143 1 2.70687 0.36713 0.66313 0.08993 0.96438 0.21566 0.23529 0.05261 59769.105616 0.000683 0.22278 0.05555 0.97872 1 3.15308 0.33586 0.77500 0.08255 0.70245 0.15836 0.17264 0.03891 59769.106967 0.000668 0.26394 0.06284 0.96005 1 3.18252 0.35708 0.78313 0.08786 0.83998 0.17639 0.20700 0.04346
