It will be possible to consider incorporating in SWIFT a level of adaptive correction for correlated image motion (due to drive errors and telescope vibrations). We will also investigate higher-order adaptive correction for low altitude turbulence (Chun et al, 1998) which correlates well over an extended field. The very large corrected field of SWIFT, offering access to a number of bright stars in almost any observation, will be a significant advantage in wavefront analysis for partial, wide-field adaptive correction. The baseline budget below does not include adaptive correction.
