/* ** ** 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 57189.673045 0.000596 0.70392 0.20768 1.00000 1 0.58845 0.11325 0.27693 0.05329 0.41422 0.09263 0.19512 0.04363 57189.674425 0.000784 0.53672 0.14665 0.96296 1 0.63269 0.10402 0.30204 0.04966 0.33958 0.07411 0.16154 0.03525 57189.675834 0.000625 0.67965 0.19899 1.00000 1 0.58420 0.11041 0.27317 0.05162 0.39705 0.08879 0.18605 0.04160 57189.677228 0.000770 0.66887 0.18937 1.00000 1 0.50752 0.09155 0.23750 0.04284 0.33947 0.07408 0.15849 0.03459 57189.678841 0.000842 0.69632 0.20479 0.98276 1 0.42913 0.08119 0.19998 0.03783 0.29881 0.06728 0.13947 0.03140 57189.680526 0.000842 0.42540 0.11406 0.98276 1 0.70393 0.10411 0.32768 0.04845 0.29945 0.06697 0.14035 0.03138 57189.682341 0.000973 0.60908 0.14165 0.98628 1 0.65232 0.09571 0.30655 0.04497 0.39731 0.07169 0.18689 0.03371
