PoincareSection is a setting for the option TrekGenerator that specifies that the Poincaré section for differential equations is used to generate treks.
ErrorBarFunction is an option for ErrorListPlot that specifies a function to apply to determine the shape of error bars.
ErrorListPlot[{{y_1, dy_1}, {y_2, dy_2}, ...}] plots points corresponding to a list of values y_1, y_2, ..., with corresponding error bars. The errors have magnitudes dy_1, ...
