Scientific paper
We review the motivations for dithering exposures with the ACS, discuss possible strategies for combining dithered exposures automatically and the implementation of dither patterns in RPS2. We recommend the development of an easy to use, standalone tool based on a version of Drizzle. We discuss the benefits of different methods to derive image offsets and identify a strategy for an automated quick-look combination. Presently, it appears to be impractical to carry out automatically in the pipeline the final, science grade, reconstruction of a dithered set of exposures. Finally, we recommend a set of DITHER PATTERN macros based on an enhancement of existing patterns for other instruments.
