/* ** ** 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 55952.466066 0.001293 0.35731 0.09280 0.95506 1 0.34385 0.04541 0.26227 0.03463 0.12286 0.02748 0.09412 0.02105 55952.468419 0.001060 0.47587 0.12991 0.98630 1 0.30353 0.04753 0.23371 0.03659 0.14444 0.03230 0.11111 0.02485 55952.470525 0.001046 0.44746 0.12270 1.00000 1 0.31989 0.05022 0.24727 0.03882 0.14314 0.03218 0.11055 0.02485 55952.472646 0.001075 0.45231 0.12243 1.00000 1 0.30854 0.04706 0.23889 0.03643 0.13956 0.03121 0.10811 0.02417 55952.474839 0.001118 0.36301 0.09461 0.96104 1 0.38235 0.05119 0.29813 0.03992 0.13880 0.03104 0.10811 0.02417 55952.478253 0.002295 0.39195 0.08468 0.95833 1 0.25985 0.03001 0.20212 0.02335 0.10185 0.01859 0.07925 0.01447 55952.551217 0.001206 0.40882 0.10855 0.96386 1 0.30231 0.04328 0.24450 0.03500 0.12359 0.02764 0.10000 0.02236 55952.553512 0.001089 0.36033 0.09446 0.97333 1 0.37878 0.05108 0.30137 0.04064 0.13649 0.03068 0.10904 0.02451 55952.555516 0.000915 0.42637 0.11476 1.00000 1 0.36878 0.05524 0.29866 0.04473 0.15724 0.03516 0.12699 0.02839 55952.558683 0.002251 0.34227 0.06825 0.99094 1 0.31803 0.03236 0.25883 0.02634 0.10885 0.01867 0.08854 0.01519 55952.599957 0.001133 0.53196 0.14761 0.94872 1 0.25407 0.04133 0.20213 0.03288 0.13515 0.03038 0.10757 0.02418 55952.603849 0.002760 0.42132 0.08409 0.97881 1 0.23066 0.02533 0.18351 0.02015 0.09718 0.01620 0.07743 0.01291
