/* ** ** 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 54830.215946 0.001816 0.32200 0.08373 0.98400 1 0.25044 0.03223 0.19903 0.02561 0.08064 0.01822 0.06440 0.01455 54830.219069 0.001307 0.40884 0.10849 0.98889 1 0.27608 0.03944 0.22023 0.03146 0.11287 0.02524 0.08989 0.02010 54830.222977 0.002600 0.37534 0.07587 0.98087 1 0.25836 0.02742 0.20606 0.02187 0.09698 0.01668 0.07723 0.01329 54830.285858 0.001874 0.27882 0.07086 1.00000 1 0.28176 0.03403 0.22194 0.02680 0.07856 0.01757 0.06202 0.01387 54830.290390 0.002658 0.32172 0.07268 0.98177 1 0.22689 0.02543 0.17967 0.02014 0.07300 0.01432 0.05789 0.01135 54830.356399 0.002600 0.34074 0.06727 0.97532 1 0.28411 0.02825 0.23357 0.02322 0.09681 0.01651 0.07951 0.01356
