What it is

The ORAC-DR data reduction system is intended to be a pipeline reducer for incoming data. It is in use for online data reduction at UKIRT and JCMT for a variety of instruments. There are a number of differences between the ORAC-DR method of reduction and other systems currently in use and observers should not expect ORAC-DR to behave or be used in the same way as those systems.

Firstly, ORAC-DR aims to reduce data to a point where its quality can be assessed; it will not generally produce publication-quality results (though in certain circumstances it may do). Secondly, although ORAC-DR also works offline, it is expected that observers will use their own preferred data reduction package if they wish to work interactively work on their data. The rest of this document summarizes and accounts for the operational differences between the pipeline and existing packages.
