/* ** ** 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 60052.588148 0.000494 0.34991 0.09173 1.00000 1 1.41994 0.19422 0.67186 0.09188 0.49686 0.11111 0.23530 0.05261 60052.589296 0.000654 0.37326 0.09385 1.00000 1 1.08914 0.14498 0.52790 0.07025 0.40654 0.08671 0.19556 0.04169 60052.590545 0.000596 0.53606 0.15260 1.00000 1 0.74608 0.13000 0.36213 0.06310 0.39994 0.09003 0.19390 0.04365 60052.591634 0.000494 0.47582 0.12993 1.00000 1 1.02542 0.16069 0.49545 0.07763 0.48792 0.10911 0.23530 0.05261 60052.592520 0.000392 0.52232 0.14516 0.96296 1 1.21881 0.20112 0.58999 0.09735 0.63662 0.14236 0.30769 0.06880 60052.593334 0.000421 0.41342 0.11047 0.96552 1 1.43871 0.21047 0.69444 0.10158 0.59479 0.13301 0.28572 0.06389 60052.594162 0.000407 0.66358 0.19234 0.96429 1 0.91829 0.16768 0.44445 0.08114 0.60936 0.13717 0.29443 0.06628 60052.595033 0.000465 0.50272 0.14149 1.00000 1 1.01685 0.16963 0.48663 0.08117 0.51119 0.11587 0.24686 0.05595 60052.595847 0.000349 0.67852 0.19345 1.00000 1 1.06995 0.19628 0.51956 0.09528 0.72598 0.15844 0.35000 0.07638 60052.597038 0.000842 0.43290 0.08426 0.99921 1 1.29422 0.13990 0.61694 0.06665 0.56027 0.09069 0.26658 0.04313
