/* ** ** 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 54977.658549 0.001177 0.81245 0.24671 1.00000 1 0.15043 0.03071 0.12000 0.02450 0.12222 0.02747 0.09827 0.02209 54977.662151 0.002426 0.48277 0.11651 0.99242 1 0.16360 0.02300 0.12965 0.01823 0.07898 0.01549 0.06275 0.01231 54977.725333 0.001714 0.45213 0.12294 1.00000 1 0.18616 0.02880 0.14964 0.02315 0.08417 0.01882 0.06780 0.01516 54977.729139 0.002092 0.46762 0.12120 0.97721 1 0.16660 0.02430 0.13360 0.01949 0.07791 0.01669 0.06225 0.01334 54977.792132 0.001830 0.42464 0.11302 0.96032 1 0.19373 0.02796 0.15610 0.02253 0.08227 0.01840 0.06612 0.01478 54977.795880 0.001917 0.35314 0.09259 0.99242 1 0.21461 0.02938 0.17321 0.02371 0.07579 0.01695 0.06107 0.01366
