2015-10-17

Following not updated

The sky is populated with thick dark clouds, but there is a forecast of a clear patch from 9:30 to noon.

Set Focus : we start at 0.0 mm We updated ini.pako. Remember 1mm difference between the focus of NIKA and the focus of the other IRAM instruments due to the design of the optics (SL).

Quick description of the session: focus tests.
