/* ** ** Swift/XRT hardness ratio for BL Lacertae. ** 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 55855.343572 0.000915 0.60996 0.17312 1.00000 1 0.45452 0.07944 0.20874 0.03648 0.27724 0.06200 0.12699 0.02839 55855.345417 0.000930 0.54688 0.15294 0.96875 1 0.50740 0.08519 0.23444 0.03936 0.27749 0.06206 0.12903 0.02885 55855.347363 0.001017 0.55679 0.15559 0.95714 1 0.46069 0.07629 0.21305 0.03528 0.25651 0.05774 0.11866 0.02671 55855.349513 0.001133 0.41897 0.11117 0.91026 1 0.58280 0.08183 0.26777 0.03759 0.24418 0.05497 0.11198 0.02521 55855.351488 0.000842 0.52715 0.14598 0.96552 1 0.58250 0.09515 0.26965 0.04405 0.30706 0.06866 0.14286 0.03194 55855.353231 0.000901 0.72843 0.16304 0.98104 1 0.67471 0.09848 0.31668 0.04622 0.49148 0.08340 0.22935 0.03891
