/* ** ** 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 54987.489993 0.035675 0.19345 0.03162 0.11713 1 0.67895 0.04461 0.32203 0.02113 0.13135 0.01966 0.06243 0.00933 54987.624277 0.034726 0.24804 0.04017 0.09234 1 0.62172 0.04584 0.35068 0.02561 0.15421 0.02223 0.08878 0.01268 54987.724028 0.002339 0.26626 0.05244 0.96787 1 0.67562 0.06132 0.31794 0.02885 0.17989 0.03144 0.08440 0.01475 54987.785194 0.001670 0.24566 0.06039 1.00000 1 0.64851 0.07164 0.29735 0.03284 0.15932 0.03499 0.07262 0.01594 54987.789958 0.003094 0.17802 0.03498 0.96548 1 0.72999 0.05567 0.33655 0.02567 0.12995 0.02354 0.05983 0.01083 54987.856993 0.003399 0.17600 0.03327 0.98610 1 0.70323 0.05175 0.32561 0.02396 0.12377 0.02155 0.05720 0.00996 54987.958450 0.035279 0.15438 0.02664 0.10961 1 0.65344 0.04160 0.39200 0.02440 0.10087 0.01618 0.06142 0.00962
