/* ** ** 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 58130.288838 0.000988 0.30173 0.07727 0.95588 1 1.72762 0.21000 0.40512 0.04924 0.52127 0.11749 0.12220 0.02754 58130.291279 0.001453 0.16221 0.03917 0.98000 1 2.18235 0.19883 0.50536 0.04604 0.35400 0.07916 0.08163 0.01825 58130.293908 0.001177 0.19233 0.04744 0.96296 1 2.25926 0.22653 0.52782 0.05292 0.43452 0.09792 0.10183 0.02295 58130.296290 0.001206 0.26366 0.06721 0.98795 1 1.58129 0.18848 0.36735 0.04379 0.41692 0.09394 0.09686 0.02183 58130.298730 0.001235 0.40806 0.08745 0.97455 1 1.57245 0.18383 0.36614 0.04280 0.64165 0.11525 0.14969 0.02689
