/* ** ** 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 58161.435190 0.000544 0.39226 0.06681 0.98404 0 1.58874 0.14432 1.36327 0.12384 0.62320 0.08979 0.53272 0.07674 58161.436162 0.000428 0.52241 0.09332 1.00000 0 1.47004 0.15532 1.27381 0.13458 0.76796 0.11062 0.66590 0.09592 58161.437068 0.000477 0.48226 0.08340 0.98788 0 1.48889 0.14816 1.27256 0.12662 0.71804 0.10156 0.61452 0.08691 58161.437852 0.000307 0.25434 0.06330 1.00000 0 1.78366 0.20275 1.54180 0.17526 0.45366 0.10045 0.39181 0.08676 58161.438778 0.000619 0.34558 0.05722 0.97196 0 1.60715 0.13603 1.38661 0.11737 0.55539 0.07904 0.47898 0.06815 58161.439973 0.000576 0.36040 0.05951 0.97487 0 1.66246 0.14174 1.43461 0.12231 0.59914 0.08473 0.51632 0.07302 58161.441084 0.000535 0.43854 0.07655 1.00000 0 1.41150 0.13727 1.21006 0.11765 0.61900 0.08974 0.52981 0.07679 58161.442120 0.000501 0.51577 0.09004 0.98844 0 1.34133 0.13832 1.15357 0.11897 0.69182 0.09746 0.59434 0.08372 58161.443139 0.000518 0.42945 0.07326 0.96648 0 1.55445 0.14624 1.34326 0.12637 0.66756 0.09499 0.57589 0.08194 58161.443955 0.000298 0.25876 0.06500 0.99029 0 1.76903 0.20242 1.52197 0.17413 0.45776 0.10236 0.39281 0.08784 58161.445028 0.000775 0.38202 0.05491 0.95896 0 1.62290 0.12476 1.39597 0.10732 0.61998 0.07530 0.53367 0.06482
