/* ** ** Swift/XRT hardness ratio for 3C 279. ** 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 54823.245283 0.009323 0.44166 0.08584 0.23353 1 0.29931 0.03198 0.23279 0.02485 0.13219 0.02146 0.10141 0.01645 54823.256131 0.001525 0.37039 0.09536 0.99048 1 0.28960 0.03905 0.21782 0.02937 0.10727 0.02353 0.08039 0.01763 54823.258658 0.001002 0.52322 0.14416 0.97101 1 0.30354 0.04887 0.22824 0.03674 0.15882 0.03551 0.11940 0.02670 54823.261781 0.002121 0.53566 0.12120 0.96985 1 0.21016 0.02808 0.15819 0.02114 0.11257 0.02055 0.08475 0.01547 54823.305847 0.001787 0.44870 0.10462 0.96640 1 0.25796 0.03366 0.19989 0.02607 0.11575 0.02237 0.09052 0.01749 54823.328363 0.002179 0.29260 0.06258 0.98215 1 0.34556 0.03539 0.26584 0.02722 0.10111 0.01898 0.07793 0.01463
