/* ** ** Swift/XRT hardness ratio for PKS 1830-21. ** 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 55490.448047 0.001148 3.93783 1.96903 1.00000 1 0.03120 0.01396 0.02564 0.01147 0.12288 0.02748 0.10127 0.02264 55490.450516 0.001322 4.96045 2.71938 1.00000 1 0.02148 0.01074 0.01778 0.00889 0.10656 0.02395 0.08747 0.01966 55490.452928 0.001089 1.24493 0.42793 1.00000 1 0.10339 0.02688 0.08514 0.02214 0.12871 0.02893 0.10613 0.02386 55490.455165 0.001148 1.79735 0.67471 0.96203 1 0.07117 0.02146 0.05867 0.01769 0.12792 0.02860 0.10526 0.02354 55490.457300 0.000988 2.54008 1.05537 0.98529 1 0.05967 0.02110 0.04923 0.01741 0.15157 0.03308 0.12537 0.02736 55490.514843 0.001278 1.34946 0.46011 0.98863 1 0.08649 0.02249 0.07095 0.01845 0.11671 0.02573 0.09562 0.02108 55490.516847 0.000726 1.77801 0.66869 0.96001 1 0.11284 0.03402 0.09362 0.02823 0.20064 0.04510 0.16582 0.03728 55490.519259 0.001685 0.97115 0.30711 0.98276 1 0.08729 0.01952 0.07207 0.01612 0.08478 0.01896 0.07018 0.01569 55490.521655 0.000712 4.79560 2.62681 1.00000 1 0.04130 0.02065 0.03404 0.01702 0.19806 0.04429 0.16327 0.03651 55490.523660 0.001293 2.13802 0.68850 0.98738 1 0.08024 0.02145 0.06588 0.01761 0.17156 0.03082 0.14111 0.02534
