/* ** ** Swift/XRT hardness ratio for QSO B1727+502. ** 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 57157.026400 0.001583 0.17837 0.04333 0.99083 1 1.65392 0.15694 0.41710 0.03957 0.29501 0.06597 0.07407 0.01656 57157.028812 0.000828 0.39644 0.10466 0.94737 1 1.47862 0.20748 0.37404 0.05249 0.58618 0.13108 0.14815 0.03313 57157.031078 0.001438 0.23043 0.05750 0.97980 1 1.41183 0.15641 0.35778 0.03964 0.32533 0.07275 0.08248 0.01844 57157.034230 0.001714 0.17807 0.04217 0.94068 1 1.67002 0.15368 0.42348 0.03897 0.29738 0.06490 0.07568 0.01651 57157.037411 0.001467 0.24929 0.05804 0.96514 1 1.49291 0.15466 0.37856 0.03922 0.37217 0.07760 0.09438 0.01968 57157.082276 0.001903 0.17665 0.04297 0.97710 1 1.51136 0.14465 0.35530 0.03400 0.26698 0.05970 0.06250 0.01398 57157.086866 0.002687 0.15003 0.03434 0.97120 1 1.38824 0.11550 0.32649 0.02716 0.20828 0.04441 0.04898 0.01044
