/* ** ** 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 58139.121213 0.000356 0.53028 0.15569 0.97561 0 0.90277 0.15511 0.60228 0.10313 0.47872 0.11397 0.31610 0.07487 58139.122043 0.000475 0.37377 0.09608 0.98171 0 1.02468 0.13911 0.70220 0.09527 0.38299 0.08360 0.26130 0.05702 58139.122830 0.000312 0.63182 0.18248 0.97222 0 0.87478 0.15851 0.60204 0.10910 0.55270 0.12430 0.37955 0.08535 58139.123577 0.000434 0.38170 0.10300 0.98000 0 1.01126 0.14480 0.69964 0.10018 0.38600 0.08829 0.26675 0.06102 58139.124569 0.000558 0.36405 0.09625 0.97409 0 0.84972 0.11810 0.58404 0.08117 0.30934 0.06958 0.21199 0.04767 58139.125492 0.000365 0.42943 0.11718 0.98413 0 1.07443 0.16407 0.74427 0.11365 0.46140 0.10434 0.31968 0.07229 58139.126331 0.000475 0.35418 0.09349 0.98171 0 1.01024 0.13965 0.69892 0.09662 0.35781 0.08046 0.24754 0.05566 58139.127217 0.000411 0.43979 0.11880 0.97887 0 0.94780 0.14362 0.65462 0.09919 0.41683 0.09321 0.28825 0.06445 58139.128021 0.000394 0.44403 0.12075 0.97059 0 0.97961 0.14980 0.68198 0.10427 0.43497 0.09782 0.30192 0.06789 58139.128820 0.000405 0.44074 0.11822 0.93571 0 1.00355 0.14869 0.69490 0.10296 0.44230 0.09890 0.30585 0.06839 58139.129653 0.000428 0.52907 0.14716 0.98649 0 0.75658 0.12514 0.51899 0.08584 0.40029 0.08951 0.27443 0.06136 58139.130605 0.000524 0.35771 0.09437 0.97790 0 0.90945 0.12545 0.62946 0.08683 0.32532 0.07316 0.22516 0.05063 58139.131517 0.000388 0.44712 0.11630 0.98507 0 1.07365 0.15830 0.74317 0.10957 0.48005 0.10287 0.33227 0.07120
