/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 58138.448109 0.000327 0.47811 0.08423 0.98230 0 2.13929 0.21727 1.85701 0.18860 1.02283 0.14723 0.88836 0.12788 58138.448809 0.000373 0.37744 0.06239 0.98450 0 2.45743 0.21581 2.13302 0.18732 0.92753 0.12988 0.80449 0.11265 58138.450016 0.000833 0.50298 0.05288 0.98264 0 2.28775 0.14012 1.96249 0.12020 1.15070 0.09833 0.98528 0.08420 58138.451252 0.000402 0.40459 0.06723 0.97842 0 2.17248 0.19426 1.86639 0.16687 0.87897 0.12309 0.75125 0.10520 58138.451972 0.000318 0.44336 0.07576 0.98182 0 2.45850 0.23492 2.10622 0.20126 1.09001 0.15441 0.93640 0.13264 58138.452629 0.000339 0.42858 0.07354 0.99145 0 2.29960 0.21777 1.99356 0.18878 0.98555 0.14103 0.85455 0.12228 58138.453280 0.000312 0.39359 0.06630 0.96296 0 2.80588 0.24930 2.41841 0.21488 1.10435 0.15803 0.95315 0.13639 58138.453986 0.000394 0.35207 0.05894 0.95588 0 2.49593 0.21341 2.15229 0.18403 0.87875 0.12649 0.75852 0.10919 58138.454955 0.000576 0.45756 0.05775 0.97990 0 2.44980 0.17272 2.12173 0.14958 1.12093 0.11735 0.96988 0.10153 58138.455855 0.000324 0.44049 0.07533 0.99107 0 2.38508 0.22930 2.04756 0.19681 1.05060 0.14858 0.90240 0.12762 58138.456555 0.000376 0.39115 0.06641 0.96154 0 2.33333 0.21007 2.01816 0.18170 0.91268 0.13139 0.78886 0.11355 58138.457308 0.000376 0.41319 0.06958 0.97692 0 2.19564 0.20071 1.90810 0.17442 0.90721 0.12830 0.78871 0.11154 58138.458341 0.000657 0.38155 0.04662 0.98238 0 2.54337 0.16363 2.21221 0.14232 0.97042 0.10081 0.84412 0.08768
