    * setup representative test queries and time delay for different processing loads

+     * FPA.TEMP concept was being drawn from the database, instead of the image headers.  This seems to have been unnecessary for a long time, and switching back to a header based value does not appear to have any effect on the images or photometry for a small sample.  Removing these calls to the database have cut the load from 15-20 to ~3, largely removing potential database load issues from the list of possible bottlenecks.
