/* ** ** 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 57191.196226 0.001017 0.45439 0.12318 0.98571 1 0.31608 0.04788 0.25390 0.03846 0.14362 0.03229 0.11536 0.02593 57191.198259 0.000988 0.50904 0.14018 0.95588 1 0.29920 0.04759 0.24055 0.03826 0.15230 0.03424 0.12246 0.02753 57191.200191 0.000944 0.53910 0.14936 0.95385 1 0.29775 0.04871 0.23935 0.03916 0.16052 0.03589 0.12903 0.02885 57191.202137 0.001002 0.38817 0.10248 0.98551 1 0.37870 0.05314 0.30388 0.04264 0.14700 0.03287 0.11765 0.02631 57191.204360 0.001220 0.41351 0.11020 0.98810 1 0.29008 0.04206 0.23316 0.03380 0.11995 0.02682 0.09639 0.02155 57191.207628 0.002048 0.36147 0.07231 0.97124 1 0.34517 0.03554 0.27449 0.02826 0.12477 0.02140 0.09931 0.01703
