/* ** ** 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 57582.046811 0.000327 0.44772 0.11699 0.98230 0 2.68348 0.39077 0.88625 0.12892 1.20144 0.26067 0.39237 0.08478 57582.047748 0.000611 0.43274 0.07469 0.96209 0 3.73698 0.36054 1.12434 0.10844 1.61714 0.23146 0.48830 0.06988 57582.048862 0.000503 0.36867 0.07690 0.95402 0 3.63439 0.39976 1.07134 0.11783 1.33989 0.23748 0.39198 0.06947 57582.049762 0.000396 0.30185 0.08102 0.97810 0 3.24957 0.42875 0.95699 0.12615 0.98089 0.22927 0.28735 0.06720 57582.050459 0.000301 0.40780 0.11026 0.97115 0 3.27295 0.48124 0.96528 0.14193 1.33472 0.30285 0.39154 0.08885 57582.051298 0.000538 0.59629 0.11049 0.97312 0 3.08415 0.35989 0.91498 0.10674 1.83904 0.26472 0.54478 0.07842 57582.052430 0.000593 0.59555 0.10838 0.97073 0 2.85275 0.32074 0.83767 0.09419 1.69895 0.24310 0.49812 0.07128 57582.053390 0.000367 0.34252 0.08245 0.95276 0 3.94319 0.48659 1.14653 0.14148 1.35064 0.27913 0.39305 0.08122 57582.054418 0.000660 0.41021 0.07037 0.96053 0 3.73035 0.34797 1.09697 0.10232 1.53024 0.22029 0.45025 0.06481 57582.055401 0.000324 0.34505 0.09030 0.95536 0 3.69198 0.50193 1.08336 0.14728 1.27393 0.28489 0.37446 0.08373 57582.056680 0.000955 0.55708 0.07918 0.95152 0 3.04718 0.26181 0.89396 0.07680 1.69753 0.19222 0.49764 0.05635
