The travel of the autoguider probe defines a semi-annulus (see above). Note, however, that the probe can obstruct the slit-viewing optics (not the slit itself) for θ< 30000, giving an additional azimuth restriction. The excluded inner region (a circle) is treated as a special case of the ellipse mentioned earlier, with l = m.
