/* ** ** 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 54939.852924 0.001453 0.53052 0.14694 0.99000 1 0.23790 0.03884 0.15274 0.02491 0.12621 0.02824 0.08081 0.01807 54939.855626 0.001249 0.68497 0.19947 1.00000 1 0.21497 0.04006 0.13929 0.02596 0.14725 0.03295 0.09302 0.02080 54939.858981 0.002106 0.52040 0.11221 0.99065 1 0.27245 0.03466 0.17605 0.02240 0.14178 0.02468 0.09189 0.01600 54939.921113 0.000944 0.58420 0.16234 1.00000 1 0.27716 0.04768 0.22230 0.03824 0.16191 0.03533 0.12923 0.02820 54939.923437 0.001380 0.40360 0.10709 0.98947 1 0.26245 0.03749 0.21075 0.03011 0.10592 0.02369 0.08511 0.01903 54939.926618 0.001801 0.50512 0.11270 0.95161 1 0.25029 0.03210 0.20132 0.02582 0.12642 0.02308 0.10170 0.01857 54939.987905 0.001104 0.49543 0.13674 1.00000 1 0.26223 0.04199 0.21081 0.03376 0.12992 0.02920 0.10473 0.02354 54939.989749 0.000741 0.89500 0.27715 0.98039 1 0.22114 0.04737 0.17877 0.03830 0.19792 0.04426 0.16000 0.03578 54939.992117 0.001627 0.37074 0.08763 0.98434 1 0.30266 0.03813 0.24466 0.03082 0.11221 0.02244 0.09071 0.01814
