/* ** ** 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 55744.430610 0.001046 0.76689 0.23096 0.95833 1 0.20649 0.04132 0.14926 0.02985 0.15835 0.03564 0.11535 0.02593 55744.433051 0.001394 0.59653 0.16928 0.97917 1 0.20356 0.03556 0.14304 0.02498 0.12143 0.02716 0.08511 0.01903 55744.435912 0.001467 0.58542 0.16183 0.98020 1 0.20256 0.03407 0.14422 0.02425 0.11858 0.02601 0.08444 0.01852 55744.438890 0.001511 0.54811 0.15284 0.98077 1 0.20116 0.03317 0.14329 0.02363 0.11026 0.02479 0.07803 0.01754 55744.442173 0.001772 0.58663 0.16680 0.99180 1 0.15643 0.02723 0.11187 0.01947 0.09177 0.02063 0.06578 0.01479 55744.446269 0.002324 0.62874 0.13616 0.97283 1 0.19941 0.02699 0.14326 0.01939 0.12538 0.02119 0.08994 0.01520
