/* ** ** 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 57930.270169 0.000799 0.58018 0.16446 0.94545 1 0.55374 0.09537 0.26567 0.04574 0.32127 0.07234 0.15287 0.03442 57930.271651 0.000683 0.58712 0.16483 0.95745 1 0.62334 0.10579 0.30325 0.05146 0.36597 0.08184 0.17778 0.03975 57930.273060 0.000726 0.49811 0.13887 1.00000 1 0.65315 0.10738 0.32174 0.05289 0.32534 0.07325 0.15899 0.03579 57930.274541 0.000755 0.58494 0.16697 1.00000 1 0.53762 0.09436 0.26197 0.04598 0.31448 0.07079 0.15287 0.03442 57930.276299 0.001002 0.34035 0.08843 1.00000 1 0.69698 0.09219 0.33894 0.04482 0.23722 0.05305 0.11594 0.02593 57930.278027 0.000726 0.57679 0.16423 0.98000 1 0.57889 0.10203 0.28365 0.04999 0.33390 0.07467 0.16327 0.03651 57930.279814 0.001060 0.46537 0.11521 0.98362 1 0.59384 0.08316 0.28733 0.04023 0.27636 0.05642 0.13370 0.02729
