/* ** ** 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 55614.490898 0.000370 0.31879 0.05224 0.99219 0 2.88513 0.23465 2.46601 0.20054 0.91974 0.13086 0.78451 0.11162 55614.492325 0.001050 0.48357 0.04187 0.97245 0 2.71755 0.13408 2.33424 0.11517 1.31414 0.09349 1.12899 0.08032 55614.494414 0.001039 0.48562 0.04229 0.99164 0 2.68526 0.13433 2.30738 0.11543 1.30401 0.09295 1.12060 0.07988 55614.495780 0.000327 0.35282 0.05935 0.97345 0 2.93715 0.25094 2.52544 0.21576 1.03629 0.15016 0.89120 0.12914 55614.497105 0.000998 0.48263 0.04195 0.97971 0 2.83447 0.14067 2.43603 0.12090 1.36801 0.09762 1.17593 0.08391 55614.499240 0.001137 0.42012 0.03573 0.97201 0 2.87605 0.13258 2.47305 0.11400 1.20828 0.08635 1.03909 0.07426 55614.500684 0.000307 0.34041 0.05633 0.99057 0 3.24233 0.27399 2.78786 0.23558 1.10371 0.15704 0.94889 0.13501 55614.502044 0.001053 0.45457 0.03911 0.98077 0 2.84797 0.13696 2.44954 0.11780 1.29459 0.09238 1.11335 0.07944 55614.503633 0.000535 0.38648 0.04820 0.96216 0 3.08953 0.20246 2.65410 0.17392 1.19403 0.12669 1.02570 0.10883
