/* ** ** 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 57924.055625 0.000926 0.20549 0.05101 0.95938 0 0.86958 0.08872 0.62801 0.06408 0.17869 0.04043 0.12905 0.02920 57924.057841 0.001291 0.12988 0.03094 0.96413 0 0.99335 0.08149 0.71739 0.05885 0.12902 0.02885 0.09318 0.02084 57924.059783 0.000651 0.32644 0.08062 0.96274 0 0.86303 0.10758 0.62328 0.07769 0.28173 0.06006 0.20346 0.04338 57924.107759 0.000764 0.20399 0.05079 0.95833 0 1.00751 0.10466 0.76772 0.07975 0.20552 0.04650 0.15661 0.03543 57924.109241 0.000718 0.18974 0.04669 0.97177 0 1.14350 0.11410 0.87135 0.08694 0.21697 0.04880 0.16533 0.03719 57924.111567 0.001609 0.17704 0.03178 0.96763 0 1.01819 0.07221 0.77586 0.05503 0.18026 0.02973 0.13736 0.02265
