6.2.8 Further notes on processing of OM image data

With the default settings, omichain overwrites temporary files at several stages, e.g when looping over multiple exposures or even within the analysis of a single window. This can be avoided by specifying unique output file names. It is recommended to clear out (removing or renaming) products of previous omichain runs before re-invoking omichain.
