/* ** ** 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 55491.517144 0.001438 1.10788 0.36089 0.97980 1 0.09257 0.02182 0.07423 0.01750 0.10256 0.02306 0.08206 0.01845 55491.519686 0.001104 2.27153 0.91931 0.97368 1 0.05915 0.01995 0.04746 0.01601 0.13436 0.03005 0.10811 0.02417 55491.521807 0.001017 3.25949 1.51062 1.00000 1 0.04565 0.01864 0.03636 0.01485 0.14879 0.03263 0.11942 0.02619 55491.524944 0.002121 1.44896 0.38632 0.95602 1 0.08413 0.01717 0.06733 0.01374 0.12190 0.02091 0.09744 0.01671 55491.584200 0.001133 2.73788 1.20242 1.00000 1 0.04574 0.01729 0.03733 0.01411 0.12524 0.02801 0.10256 0.02293 55491.586451 0.001118 1.58814 0.58311 0.98701 1 0.08054 0.02345 0.06611 0.01925 0.12791 0.02860 0.10526 0.02354 55491.588950 0.001380 2.34495 0.98097 0.97895 1 0.04469 0.01580 0.03678 0.01300 0.10479 0.02343 0.08602 0.01924 55491.591681 0.001351 2.48047 0.84881 0.98305 1 0.06657 0.01939 0.05471 0.01593 0.16512 0.02966 0.13563 0.02436
