/* ** ** 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 55984.507480 0.001525 0.20021 0.04917 1.00000 1 1.48620 0.15102 0.38055 0.03867 0.29756 0.06654 0.07619 0.01704 55984.510705 0.001699 0.15543 0.03746 1.00000 1 1.71811 0.15463 0.43993 0.03959 0.26704 0.05971 0.06838 0.01529 55984.514874 0.002469 0.23174 0.04649 0.95046 1 1.28730 0.11267 0.32962 0.02885 0.29832 0.05385 0.07639 0.01379 55984.566082 0.000049 0.11232 0.08396 0.98583 0 2.44694 0.59347 2.12790 0.51609 0.27484 0.19434 0.23900 0.16900 55984.567137 0.000988 0.33121 0.08590 0.97059 1 1.40680 0.18058 0.36332 0.04664 0.46595 0.10500 0.12033 0.02712 55984.569882 0.001758 0.15759 0.03704 0.98347 1 1.73446 0.15137 0.44794 0.03909 0.27333 0.05964 0.07059 0.01540 55984.572860 0.001220 0.29114 0.07230 0.96429 1 1.37925 0.16352 0.35620 0.04223 0.40155 0.08763 0.10370 0.02263 55984.576244 0.002164 0.24254 0.04449 0.97315 1 1.62951 0.13265 0.42083 0.03426 0.39522 0.06497 0.10207 0.01678
