/* ** ** 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 58528.426269 0.000408 0.41973 0.07141 0.96454 0 2.02166 0.18852 1.74792 0.16297 0.84855 0.12076 0.73245 0.10424 58528.427247 0.000570 0.23069 0.03629 0.99492 0 2.56973 0.17707 2.21161 0.15239 0.59281 0.08384 0.51105 0.07227 58528.428266 0.000448 0.33253 0.05443 0.98065 0 2.28635 0.18841 1.98133 0.16328 0.76028 0.10752 0.65899 0.09320 58528.429062 0.000347 0.47498 0.08449 0.98333 0 1.99609 0.20011 1.72756 0.17319 0.94810 0.13932 0.82071 0.12060 58528.429851 0.000443 0.37634 0.06294 0.96732 0 2.06509 0.18137 1.78763 0.15700 0.77718 0.11061 0.67306 0.09579 58528.430633 0.000339 0.51505 0.09058 0.99145 0 1.93760 0.20256 1.67656 0.17527 0.99797 0.14113 0.86351 0.12212 58528.431347 0.000376 0.43759 0.07421 0.96923 0 2.09868 0.19646 1.81673 0.17006 0.91837 0.12988 0.79497 0.11243 58528.432129 0.000405 0.32586 0.05434 0.98571 0 2.53171 0.21227 2.19063 0.18367 0.82498 0.11891 0.71381 0.10289 58528.432881 0.000347 0.50981 0.08952 0.99167 0 1.89770 0.19521 1.64195 0.16890 0.96747 0.13769 0.83708 0.11913 58528.433619 0.000391 0.38813 0.06452 0.95556 0 2.31036 0.20184 2.00017 0.17474 0.89672 0.12682 0.77649 0.10981 58528.434403 0.000394 0.39016 0.06603 0.98529 0 2.18975 0.19742 1.89471 0.17082 0.85435 0.12236 0.73925 0.10588 58528.435317 0.000521 0.30654 0.04985 0.97222 0 2.14594 0.16879 1.85693 0.14606 0.65782 0.09362 0.56922 0.08101 58528.436660 0.000822 0.36479 0.04464 0.97887 0 2.11336 0.13367 1.82165 0.11521 0.77093 0.08077 0.66420 0.06958
