Files generated during ORAC-DR imaging data reduction have suffices denoting the processing step that created them. This appendix contains a list with short descriptions of what they mean. Most will be removed once a recipe has finished using them. So you will probably only see these files if you list the contents of directory $ORAC_DATA_OUT while the pipeline is running, or you interrupt the pipeline with CTRL/C, or something has gone wrong with the the recipe and pipeline has aborted, or you have commented out the `_TIDY' primitive from the recipe, or you have set the ORAC_KEEP environment variable to 1.
