As a follow up question, what would be the recommended way of performing
calculations on array data within the EPICS database?  Do I have to
resort to subRoutine records?  In my individual channels of data
(subArray records) I have multiple quartets of data, one for for each
turn captured, I need to perform calculations on each of these quartets
to determine beam position for each turn.

General calculations can be done with the aCalcout record (SynApps). But as far as I know you cannot do iterations over n-tuples in an array.

Since you have to calculate 2 (mabye 3) values simultaneously out of 4 inputs you are probably served best with the genSub (or aSub if you have base 3.14.11)
