... Many options allow to run emchain on a subset of the data, restart from previous output, change the options of constituent tasks. The exposures , instruments and ccds parameters allow to run emchain on a subset of the data files (select an explicit list of exposures, instruments or CCDs). ... This is similar to passing backgroundset to emenergy , but allows to save all such files under a different name. emchain normally ignores data obtained with CCD read-out gain set to low (/10). ...
