Pointing errors in cross-elevation (XEL, upper panel) and elevation (EL, lower panel) due to 10 ms⁻¹ static wind for different telescope elevation pointings and relative azimuthal angles for the wind. The diagram shows elevation and cross-elevation pointing errors separately (cross-elevation is the axis of rotation perpendicular to the elevation axis, the position of which is defined by the current elevation angle). The abscissa shows the wind azimuth angle of attack. The ordinate indicates the directional error in arcseconds. Each line represents the pointing error for a specific elevation angle of the telescope.
