Flemming, thank you. Tim and Alexei, do you have inner and outer RDO to weight them ?

So Yuri
The itpc rdo's are smaller than the DAQ 1000 on the outer sectors
we should weigh one of the new RDO's and use as material something
similar to what
was use in outer RDO (g10,+cu+si in some mixture maybe)
