/* ** ** 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 54832.161376 0.001482 0.40359 0.10785 0.98039 1 0.24524 0.03498 0.19645 0.02802 0.09898 0.02237 0.07921 0.01790 54832.165008 0.002150 0.49835 0.10908 0.92394 1 0.23600 0.03027 0.18776 0.02408 0.11761 0.02086 0.09332 0.01655 54832.227590 0.001002 0.54108 0.15180 0.97101 1 0.30346 0.05089 0.22032 0.03693 0.16420 0.03693 0.11881 0.02671 54832.231309 0.002716 0.33312 0.07396 0.96644 1 0.25123 0.02781 0.17907 0.01983 0.08369 0.01611 0.05976 0.01150 54832.296266 0.004430 0.40528 0.08794 0.97270 1 0.17474 0.02004 0.10307 0.01179 0.07082 0.01305 0.04032 0.00739 54832.362272 0.000813 0.85837 0.26245 1.00000 1 0.20306 0.04234 0.16727 0.03488 0.17430 0.03898 0.14286 0.03194 54832.364305 0.001220 0.51080 0.14205 1.00000 1 0.22726 0.03758 0.18633 0.03081 0.11608 0.02596 0.09524 0.02130 54832.366731 0.001206 0.62368 0.17282 0.99402 1 0.20908 0.03674 0.16987 0.02986 0.13040 0.02793 0.10618 0.02275
