/* ** ** 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 58252.158745 0.000422 0.45236 0.07722 0.95205 0 1.85528 0.17739 1.59395 0.15240 0.83926 0.11869 0.72062 0.10191 58252.159584 0.000411 0.40673 0.06881 0.98592 0 2.03592 0.18633 1.74954 0.16012 0.82807 0.11782 0.71164 0.10126 58252.160333 0.000339 0.47766 0.08238 0.95726 0 2.17663 0.21487 1.87190 0.18479 1.03969 0.14703 0.89435 0.12648 58252.161207 0.000535 0.36267 0.05964 0.97838 0 1.80246 0.15289 1.54828 0.13133 0.65370 0.09209 0.56151 0.07910 58252.162069 0.000327 0.59824 0.10265 0.98230 0 1.92946 0.20477 1.65950 0.17612 1.15427 0.15564 0.99264 0.13385 58252.162839 0.000443 0.44977 0.07743 0.94771 0 1.76637 0.16886 1.51997 0.14530 0.79446 0.11374 0.68339 0.09784 58252.163753 0.000472 0.39421 0.06581 0.98773 0 1.88812 0.17081 1.62419 0.14693 0.74431 0.10444 0.64037 0.08985 58252.164578 0.000353 0.49545 0.08667 0.98361 0 1.95081 0.19850 1.67676 0.17061 0.96653 0.13752 0.83025 0.11813 58252.165345 0.000414 0.47842 0.08194 0.97902 0 1.77489 0.17506 1.52605 0.15052 0.84914 0.11890 0.72979 0.10219 58252.166109 0.000350 0.49382 0.08625 0.98347 0 1.98182 0.20314 1.70541 0.17480 0.97865 0.13840 0.84174 0.11904 58252.166942 0.000483 0.35661 0.06034 0.94611 0 2.01199 0.17266 1.72941 0.14841 0.71750 0.10464 0.61696 0.08998 58252.167796 0.000370 0.48373 0.08462 0.97656 0 1.90635 0.19161 1.63946 0.16478 0.92216 0.13202 0.79274 0.11349 58252.168467 0.000301 0.61892 0.11380 0.98077 0 1.81332 0.20720 1.56114 0.17838 1.12229 0.16166 0.96622 0.13918 58252.169161 0.000394 0.48038 0.08340 0.95588 0 1.85395 0.18445 1.59529 0.15872 0.89059 0.12672 0.76638 0.10905 58252.170186 0.000631 0.44641 0.06241 0.95872 0 1.87254 0.14761 1.61129 0.12701 0.83592 0.09652 0.71890 0.08301
