/* ** ** 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 56358.523084 0.000350 0.34262 0.05653 0.99174 0 2.82844 0.23607 2.41936 0.20192 0.96907 0.13792 0.83022 0.11813 56358.524594 0.001160 0.41417 0.03502 0.97007 0 2.88848 0.13222 2.48363 0.11369 1.19633 0.08503 1.02819 0.07308 56358.526113 0.000359 0.34798 0.05786 0.98387 0 2.70587 0.22873 2.33397 0.19729 0.94160 0.13481 0.81217 0.11628 56358.526932 0.000460 0.44359 0.06125 0.97484 0 2.60482 0.19948 2.22897 0.17068 1.15549 0.13275 0.98823 0.11352 56358.527760 0.000367 0.40743 0.06296 0.96850 0 2.82029 0.23556 2.40699 0.20104 1.14906 0.14938 0.98033 0.12744 56358.528726 0.000599 0.43692 0.05313 0.99034 0 2.59989 0.17312 2.22842 0.14838 1.13594 0.11558 0.97304 0.09901 56358.529640 0.000315 0.39654 0.06754 0.97248 0 2.73195 0.24819 2.34051 0.21264 1.08334 0.15606 0.92966 0.13393 56358.530320 0.000365 0.40000 0.06081 0.99206 0 2.85496 0.23298 2.46247 0.20095 1.14198 0.14648 0.98500 0.12634 56358.531006 0.000321 0.41970 0.07034 0.97297 0 2.66613 0.24426 2.27152 0.20808 1.11898 0.15704 0.95455 0.13395 56358.531692 0.000365 0.41303 0.06338 0.97619 0 2.77635 0.23205 2.39481 0.20016 1.14672 0.14756 0.98913 0.12728 56358.533035 0.000978 0.37847 0.03647 0.97337 0 2.83392 0.14291 2.42027 0.12204 1.07254 0.08807 0.91569 0.07518
