/* ** ** 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 57554.760051 0.000032 0.18750 0.11797 0.94068 0 3.62598 0.90649 3.09745 0.77436 0.67987 0.39252 0.58077 0.33531 57554.761058 0.000959 0.15470 0.03709 0.95455 1 3.26815 0.28269 0.82080 0.07100 0.50558 0.11305 0.12698 0.02839 57554.762815 0.000799 0.21988 0.05438 0.96364 1 2.71573 0.28694 0.68574 0.07245 0.59715 0.13353 0.15094 0.03375 57554.765139 0.001525 0.11868 0.02579 0.97864 1 3.07973 0.21846 0.78245 0.05550 0.36551 0.07509 0.09287 0.01908 57554.888030 0.000205 0.21640 0.05170 0.96003 0 3.50829 0.35539 2.95630 0.29945 0.75918 0.16427 0.63831 0.13809 57554.889005 0.000755 0.20467 0.05054 1.00000 1 2.98903 0.31316 0.75196 0.07878 0.61177 0.13681 0.15385 0.03440 57554.890516 0.000755 0.21332 0.05353 1.00000 1 2.84848 0.31428 0.71211 0.07855 0.60765 0.13695 0.15271 0.03442 57554.892491 0.001220 0.18317 0.03649 0.99759 1 3.12791 0.24896 0.78090 0.06214 0.57295 0.10462 0.14320 0.02614
