/* ** ** 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 56519.776404 0.000929 0.54167 0.15146 0.95950 0 0.32249 0.05413 0.23966 0.04022 0.17468 0.03906 0.13009 0.02909 56519.778160 0.000828 0.53355 0.14920 0.95455 0 0.36728 0.06099 0.27399 0.04549 0.19596 0.04409 0.14592 0.03283 56519.779714 0.000726 0.69912 0.20701 0.98805 0 0.30684 0.05906 0.23017 0.04430 0.21451 0.04827 0.16063 0.03614 56519.781135 0.000694 0.78609 0.23586 0.97500 0 0.29135 0.05828 0.21870 0.04374 0.22903 0.05122 0.17123 0.03829 56519.782596 0.000767 0.68903 0.20175 0.96226 0 0.30820 0.05773 0.22871 0.04283 0.21236 0.04779 0.15622 0.03515 56519.784390 0.001027 0.79330 0.21886 0.96056 0 0.23663 0.04391 0.17664 0.03278 0.18772 0.03832 0.14100 0.02878
