/* ** ** 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 60031.408717 0.000683 0.21330 0.05275 0.97872 1 3.77525 0.39833 0.80890 0.08533 0.80528 0.18009 0.17391 0.03889 60031.410562 0.001162 0.11995 0.02864 0.98750 1 3.86499 0.30503 0.84082 0.06636 0.46360 0.10447 0.10054 0.02266 60031.412436 0.000712 0.19526 0.04698 0.97959 1 4.14470 0.41986 0.89352 0.09050 0.80930 0.17662 0.17500 0.03819 60031.413787 0.000639 0.21040 0.05228 0.97727 1 4.03919 0.42306 0.87756 0.09191 0.84984 0.19148 0.18472 0.04162 60031.415050 0.000625 0.22666 0.05634 0.97674 1 3.87996 0.42122 0.83903 0.09107 0.87943 0.19666 0.19048 0.04259 60031.416866 0.001191 0.25426 0.04792 0.96746 1 3.24670 0.27646 0.70670 0.06017 0.82550 0.13878 0.18008 0.03027
