1) Large Map Mode. This is a raster-scanned map and is the ONLY way of making maps larger than the observing modes given below.
2) Photometry mode. In photometry mode the telescope follows a pre-determined Lissajous pattern to map a 30″ diameter region of sky.
3) Small Map Mode. This is a specialized multi-Lissajous map designed to image a 1.5 arcminute diameter region with uniform sensitivity.
4) Rastajous Map Mode. This observing mode combines the raster-scan mode and a Lissajous pattern to produce a 5′ diameter map assuming a fixed 20 sq. arcmin map area.
