/* ** ** 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 54978.253158 0.001975 0.40447 0.10775 0.98529 1 0.18438 0.02634 0.14737 0.02105 0.07458 0.01677 0.05939 0.01335 54978.257051 0.001917 0.36786 0.09725 1.00000 1 0.20909 0.02906 0.16345 0.02271 0.07692 0.01730 0.06029 0.01356 54978.261423 0.002455 0.41056 0.09100 0.99130 1 0.21225 0.02545 0.16864 0.02022 0.08714 0.01624 0.06899 0.01286 54978.323851 0.005999 0.49085 0.10465 0.98924 1 0.18710 0.02288 0.06641 0.00811 0.09184 0.01604 0.03223 0.00562 54978.387616 0.001714 0.42374 0.11406 1.00000 1 0.19723 0.02955 0.15996 0.02396 0.08358 0.01869 0.06780 0.01516 54978.392904 0.003573 0.22814 0.05284 0.98371 1 0.20624 0.02080 0.16655 0.01680 0.04705 0.00981 0.03802 0.00793
