/* ** ** 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 55484.688552 0.000944 2.66775 1.10847 0.96923 1 0.06218 0.02199 0.05000 0.01768 0.16589 0.03620 0.13333 0.02910 55484.690629 0.001133 2.02871 0.78572 0.97436 1 0.06402 0.02025 0.05195 0.01643 0.12988 0.02904 0.10526 0.02354 55484.692852 0.001089 1.50287 0.53812 0.97333 1 0.09077 0.02538 0.07268 0.02032 0.13641 0.03051 0.10959 0.02451 55484.694609 0.000668 9.29608 6.89441 1.00000 1 0.02342 0.01656 0.01860 0.01316 0.21776 0.04870 0.17391 0.03889 55484.697631 0.002353 1.22133 0.31486 0.98483 1 0.08682 0.01671 0.06944 0.01336 0.10603 0.01819 0.08524 0.01462 55484.755722 0.001206 2.75809 1.22546 0.98795 1 0.04702 0.01805 0.03494 0.01341 0.12969 0.02901 0.09756 0.02182 55484.758394 0.001467 1.69388 0.63984 0.98020 1 0.06505 0.01980 0.04740 0.01443 0.11019 0.02464 0.08081 0.01807 55484.761953 0.002092 1.98092 0.58568 0.91676 1 0.07268 0.01763 0.05354 0.01299 0.14397 0.02434 0.10605 0.01793
