NIKA October 16th, 2015 / S8

Back to list of day to day logbook of observations

2015-10-16


Following not updated

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).

Miscom between us: we had focalized on the 1mm and continued to the mini session applying the pointing correction for the 1mm, whereas we want the ref on the 2mm. Not catastrophic because we have the record of the pointing correction recommended by the reduction analysis, but from now on we apply the 2mm corrections.
