/* ** ** 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 58570.330801 0.000483 0.44396 0.07672 0.95210 0 1.65821 0.15839 1.39785 0.13351 0.73618 0.10602 0.62000 0.08928 58570.331842 0.000558 0.31966 0.05223 0.97409 0 1.98202 0.16223 1.67189 0.13684 0.63356 0.08961 0.53280 0.07535 58570.332820 0.000420 0.41543 0.07073 0.95172 0 2.07002 0.19086 1.72671 0.15921 0.85994 0.12310 0.71818 0.10279 58570.333535 0.000295 0.22311 0.05610 0.99020 0 2.08074 0.22516 1.75263 0.18965 0.46423 0.10537 0.39147 0.08886 58570.334134 0.000304 0.23792 0.05941 0.96190 0 1.99850 0.22207 1.67310 0.18585 0.47549 0.10633 0.39670 0.08870 58570.334918 0.000480 0.39894 0.06737 0.97590 0 1.85702 0.16895 1.54198 0.14026 0.74085 0.10541 0.61505 0.08750 58570.335945 0.000547 0.38774 0.06525 0.96296 0 1.67646 0.15064 1.41188 0.12686 0.65003 0.09250 0.54746 0.07789 58570.337065 0.000573 0.30828 0.05130 0.98485 0 1.95081 0.15972 1.63279 0.13368 0.60140 0.08712 0.50283 0.07285 58570.337962 0.000324 0.27174 0.06974 0.96429 0 1.58975 0.19036 1.34715 0.16131 0.43200 0.09806 0.36609 0.08310 58570.338839 0.000553 0.31388 0.05168 0.99476 0 1.96080 0.15955 1.66234 0.13527 0.61545 0.08809 0.52163 0.07466 58570.340013 0.000622 0.28685 0.04610 0.95349 0 2.01391 0.15379 1.70281 0.13003 0.57768 0.08170 0.48862 0.06910 58570.341049 0.000414 0.47423 0.08399 0.97902 0 1.73959 0.17495 1.46843 0.14768 0.82498 0.12026 0.69660 0.10154 58570.341906 0.000443 0.50275 0.08623 0.98039 0 1.62837 0.16438 1.38136 0.13944 0.81866 0.11353 0.69449 0.09631
