/* ** ** Swift/XRT hardness ratio for 3C 66A. ** 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 54742.291587 0.002847 0.17065 0.03238 0.97852 1 0.48820 0.03554 0.40129 0.02922 0.08331 0.01460 0.06841 0.01198 54742.363114 0.003544 0.13513 0.02597 0.98253 1 0.49429 0.03303 0.38018 0.02541 0.06679 0.01204 0.05156 0.00929 54742.428195 0.001278 0.24164 0.05898 0.98864 1 0.48798 0.05335 0.39948 0.04367 0.11791 0.02573 0.09655 0.02107 54742.433482 0.004009 0.11292 0.02222 0.97684 1 0.46533 0.02938 0.38024 0.02401 0.05254 0.00979 0.04288 0.00799 54742.496763 0.003210 0.11986 0.02319 0.99440 1 0.55104 0.03526 0.45550 0.02914 0.06605 0.01206 0.05460 0.00997 54743.332877 0.036565 0.15819 0.02545 0.11666 1 0.46863 0.02795 0.38701 0.02308 0.07413 0.01108 0.06115 0.00914 54743.433578 0.003239 0.13187 0.02712 0.97650 1 0.57714 0.04056 0.37303 0.02619 0.07611 0.01471 0.04941 0.00955 54743.500576 0.003559 0.15600 0.02935 0.98367 1 0.42388 0.02963 0.34898 0.02439 0.06613 0.01155 0.05461 0.00954
