/* ** ** 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 56747.986344 0.001104 0.56782 0.15935 0.98684 1 0.23680 0.04015 0.18865 0.03198 0.13446 0.03007 0.10667 0.02385 56747.988697 0.001249 0.41998 0.10921 0.96512 1 0.30089 0.04255 0.24096 0.03408 0.12637 0.02758 0.10120 0.02208 56747.991326 0.001380 0.36798 0.09643 0.98947 1 0.28935 0.03953 0.23140 0.03161 0.10648 0.02381 0.08511 0.01903 56747.993825 0.001118 0.35230 0.09219 0.98701 1 0.37538 0.05101 0.29917 0.04065 0.13225 0.02957 0.10526 0.02354 56747.996134 0.001191 0.42152 0.11390 0.97561 1 0.29330 0.04344 0.23487 0.03479 0.12363 0.02794 0.09900 0.02237 56748.163550 0.166225 0.42813 0.08609 0.01494 1 0.26275 0.02914 0.19390 0.02139 0.11249 0.01887 0.08425 0.01404
