/* ** ** 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 54956.174963 0.002862 0.12189 0.02911 0.97970 1 0.92530 0.07355 0.33709 0.02678 0.11278 0.02540 0.04120 0.00927 54956.182313 0.004488 0.10353 0.02021 0.97882 1 1.01482 0.06096 0.37224 0.02236 0.10507 0.01952 0.03835 0.00712 54956.241558 0.002077 0.14805 0.03551 0.98601 1 1.01000 0.08757 0.38318 0.03321 0.14954 0.03344 0.05674 0.01269 54956.246570 0.002934 0.12898 0.03066 0.95545 1 0.86149 0.06935 0.32168 0.02589 0.11112 0.02485 0.04145 0.00927 54956.251828 0.002324 0.18410 0.04294 0.96535 1 0.81985 0.07555 0.30664 0.02826 0.15093 0.03234 0.05672 0.01215 54956.308514 0.002397 0.12315 0.02928 0.98182 1 1.09664 0.08854 0.39426 0.03182 0.13505 0.03020 0.04938 0.01104 54956.321071 0.010161 0.11816 0.01945 0.55151 1 0.92032 0.04963 0.36868 0.01971 0.10874 0.01692 0.04355 0.00672
