/* ** ** 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 58582.298071 0.000298 0.28614 0.07676 0.98058 0 2.51785 0.31552 1.31463 0.16473 0.72045 0.17090 0.37619 0.08930 58582.298896 0.000527 0.34335 0.05688 0.97802 0 2.89050 0.24429 1.64097 0.13864 0.99246 0.14141 0.56526 0.08053 58582.299961 0.000538 0.33355 0.05648 0.97849 0 2.82623 0.23984 1.60350 0.13610 0.94268 0.13812 0.53329 0.07815 58582.301026 0.000527 0.34209 0.05664 0.98352 0 2.88627 0.24437 1.62856 0.13787 0.98736 0.14048 0.55670 0.07919 58582.302062 0.000509 0.47195 0.08222 0.96591 0 2.16091 0.21479 1.23367 0.12260 1.01984 0.14591 0.58312 0.08344 58582.303178 0.000608 0.34221 0.05776 0.97619 0 2.39899 0.20458 1.39094 0.11861 0.82096 0.11958 0.47599 0.06933 58582.304353 0.000567 0.34817 0.05872 0.95408 0 2.58768 0.22367 1.50085 0.12979 0.90095 0.13046 0.52457 0.07595 58582.305430 0.000509 0.35210 0.05869 0.98295 0 2.76453 0.23527 1.64636 0.14010 0.97339 0.13950 0.57860 0.08291 58582.306445 0.000506 0.40570 0.06903 0.97143 0 2.34559 0.21590 1.43601 0.13214 0.95161 0.13617 0.58312 0.08344 58582.307973 0.001021 0.34070 0.04243 0.97167 0 2.51052 0.15825 1.50905 0.09511 0.85534 0.09187 0.51378 0.05518
