/* ** ** 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 53751.175008 0.003443 0.47408 0.10778 0.99049 1 0.24563 0.03198 0.10362 0.01349 0.11645 0.02170 0.04925 0.00918 53751.241500 0.001177 0.49502 0.13580 0.97531 1 0.25951 0.04124 0.20412 0.03244 0.12846 0.02873 0.10126 0.02264 53751.244245 0.001569 0.57640 0.13515 0.99812 1 0.23785 0.03405 0.18665 0.02672 0.13710 0.02546 0.10761 0.01998 53751.308478 0.001220 0.49399 0.13544 0.98810 1 0.26339 0.04135 0.19664 0.03086 0.13011 0.02925 0.09591 0.02156 53751.311092 0.001394 0.45982 0.11098 0.97715 1 0.31598 0.04269 0.23163 0.03129 0.14529 0.02906 0.10660 0.02132 53751.580272 0.000304 0.59419 0.30684 0.98355 0 0.25725 0.08135 0.19584 0.06193 0.15285 0.06240 0.11637 0.04751
