/* ** ** 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 55794.583561 0.001758 0.32061 0.08286 0.97521 1 0.26098 0.03382 0.21166 0.02742 0.08367 0.01871 0.06780 0.01516 55794.586219 0.000901 0.88339 0.27016 1.00000 1 0.19006 0.04072 0.15366 0.03292 0.16790 0.03664 0.13548 0.02957 55794.589778 0.002658 0.41689 0.08030 0.97053 1 0.25788 0.02707 0.20943 0.02198 0.10751 0.01736 0.08714 0.01407 55794.645854 0.001699 0.40285 0.10717 0.97436 1 0.21947 0.03162 0.17358 0.02501 0.08841 0.01977 0.07018 0.01569 55794.649050 0.001496 0.45665 0.12424 0.98058 1 0.22030 0.03376 0.17294 0.02650 0.10060 0.02262 0.07882 0.01772 55794.652696 0.002150 0.30593 0.07004 0.99057 1 0.28325 0.03156 0.22351 0.02490 0.08665 0.01733 0.06821 0.01364 55794.716936 0.001932 0.35193 0.09166 0.97744 1 0.25728 0.03381 0.17710 0.02325 0.09055 0.02036 0.06123 0.01376 55794.720117 0.001249 0.49776 0.13644 0.98837 1 0.27981 0.04436 0.18777 0.02977 0.13928 0.03115 0.09412 0.02105 55794.723865 0.002498 0.38579 0.08322 0.98766 1 0.27396 0.03147 0.18290 0.02101 0.10569 0.01930 0.07064 0.01290
