/* ** ** 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 57190.198307 0.000872 0.64491 0.18729 0.98333 1 0.43672 0.08011 0.20962 0.03845 0.28165 0.06341 0.13472 0.03033 57190.199716 0.000537 1.24021 0.41859 0.97297 1 0.36961 0.09241 0.17778 0.04444 0.45840 0.10393 0.21936 0.04973 57190.201125 0.000872 0.55640 0.15772 1.00000 1 0.49348 0.08499 0.23769 0.04093 0.27457 0.06182 0.13248 0.02983 57190.202650 0.000654 1.19635 0.39150 1.00000 1 0.32375 0.07853 0.15455 0.03748 0.38732 0.08509 0.18552 0.04075 57190.204451 0.001148 0.40479 0.10812 1.00000 1 0.51965 0.07588 0.24992 0.03649 0.21035 0.04704 0.10127 0.02264 57190.206949 0.001351 0.65604 0.14791 0.98693 1 0.45721 0.06550 0.21721 0.03112 0.29995 0.05222 0.14382 0.02504
