Addition to 31 MHz plan

keyword=Addition to 31 MHz plan

At Serge's request, we will add the following two targets to the 31 MHz data-taking:

* aluminum frame * empty target

He says some studies Maud and Goulven have been doing motivate this.

Spend half hour on each of these (including the time needed to change the target).

Also, for all cases we do, please take a short (5 minute) run with fast clear disabled so we can get real rates if we need them.
