Making symmetric stacks in Mark & Find mode

This technical note describes what is probably the simplest way to take stacks at multiple positions using Mark & Find mode in the SP5 software. Using this procedure a symmetrical stack will be taken around each marked point. The instructions for this procedure are correct as of the 11th October 2016 but may need to be altered if software updates introduce changes. The procedure works on the SP5 but it should also be the same on the SPE3. If there are any differences in the procedure on the SPE3 then it will be noted.
