/* ** ** 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 55160.001898 0.000639 0.69783 0.20430 1.00000 1 0.32453 0.06133 0.26047 0.04922 0.22647 0.05064 0.18182 0.04066 55160.003452 0.000915 0.55730 0.15543 0.96825 1 0.30016 0.05003 0.23607 0.03934 0.16728 0.03741 0.13115 0.02933 55160.005994 0.001627 0.43874 0.09196 0.96218 1 0.35764 0.04175 0.27871 0.03254 0.15691 0.02732 0.12249 0.02132 55160.928140 0.001235 0.39663 0.10477 0.96471 1 0.30194 0.04245 0.24483 0.03442 0.11976 0.02678 0.09756 0.02182 55160.930246 0.000872 0.57564 0.16312 1.00000 1 0.28397 0.04943 0.23158 0.04031 0.16347 0.03655 0.13333 0.02981 55160.932062 0.000944 0.57274 0.16072 0.98462 1 0.26799 0.04543 0.21813 0.03698 0.15349 0.03432 0.12500 0.02795 55160.934197 0.001191 0.57425 0.14457 0.98397 1 0.26679 0.04079 0.21722 0.03321 0.15320 0.03064 0.12394 0.02479
