/* ** ** 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 57894.741879 0.001046 0.36649 0.09554 0.95833 1 0.40909 0.05478 0.31942 0.04277 0.14993 0.03353 0.11594 0.02593 57894.743898 0.000973 0.38035 0.10014 1.00000 1 0.40275 0.05597 0.31454 0.04371 0.15318 0.03426 0.11940 0.02670 57894.745728 0.000857 0.37527 0.09919 1.00000 1 0.46209 0.06422 0.35792 0.04974 0.17341 0.03899 0.13491 0.03033 57894.747588 0.001002 0.38395 0.10198 0.98551 1 0.39053 0.05450 0.30410 0.04243 0.14995 0.03389 0.11646 0.02632 57894.749345 0.000755 0.68533 0.20223 0.98077 1 0.29171 0.05534 0.22775 0.04320 0.19992 0.04518 0.15527 0.03509 57894.751016 0.000915 0.42641 0.11509 1.00000 1 0.38572 0.05829 0.29762 0.04498 0.16447 0.03678 0.12698 0.02839 57894.752991 0.001060 0.35507 0.09291 0.97260 1 0.40454 0.05416 0.31492 0.04216 0.14364 0.03229 0.11211 0.02520 57894.755722 0.001670 0.46409 0.09187 0.97728 1 0.37314 0.04210 0.29080 0.03281 0.17317 0.02817 0.13489 0.02194
