/* ** ** 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 58553.334910 0.000382 0.42639 0.07440 0.95455 0 4.34780 0.42153 1.83652 0.17642 1.85385 0.26897 0.78260 0.11265 58553.336010 0.000718 0.36895 0.06259 0.92742 0 3.43992 0.29922 1.15021 0.09998 1.26916 0.18485 0.42421 0.06180 58553.337161 0.000434 0.32452 0.07152 0.94000 0 3.53661 0.38898 1.21010 0.13309 1.14772 0.21919 0.39414 0.07527 58553.337899 0.000304 0.29430 0.07982 0.98095 0 3.76785 0.48960 1.24375 0.16157 1.10888 0.26400 0.36881 0.08757 58553.338810 0.000608 0.51177 0.08944 0.94286 0 2.92577 0.29673 0.99100 0.10043 1.49732 0.21311 0.50327 0.07159 58553.339777 0.000359 0.21899 0.05447 0.97581 0 4.38744 0.47743 1.50466 0.16361 0.96081 0.21490 0.33113 0.07404 58553.340703 0.000567 0.45593 0.07906 0.97449 0 3.47166 0.34336 1.14863 0.11352 1.58282 0.22546 0.52171 0.07422 58553.341571 0.000301 0.29154 0.07658 1.00000 0 3.71914 0.46971 1.28138 0.16185 1.08429 0.24975 0.37526 0.08644 58553.342216 0.000344 0.29281 0.07499 0.94118 0 3.58742 0.44758 1.22113 0.15234 1.05042 0.23494 0.35774 0.07999 58553.342980 0.000420 0.35107 0.07844 0.97241 0 3.34438 0.38779 1.12486 0.13041 1.17411 0.22425 0.39414 0.07527 58553.343747 0.000347 0.33929 0.08827 0.96667 0 2.99985 0.39847 1.01858 0.13529 1.01783 0.22767 0.34540 0.07723 58553.344412 0.000318 0.32154 0.08462 0.92727 0 3.56412 0.47521 1.20667 0.16088 1.14600 0.26003 0.38772 0.08798 58553.345037 0.000307 0.38748 0.10274 0.97170 0 2.91408 0.41520 1.00611 0.14335 1.12915 0.25250 0.38900 0.08698 58553.346270 0.000926 0.36593 0.05026 0.95938 0 3.88775 0.27732 1.32130 0.09416 1.42266 0.16696 0.47950 0.05619
