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).
Quick description of the session: focus tests.

Retrying scan after Martino tweaks codes. Seems to be related to the order in which we launch programs of the NIKA control software. |

Correcting pointing. Comparing with the beam model (SL), the 1mm profile seems consistent with the scan and the diffraction produced by the tetrapod. |

Starting mini pointing session (not the real one: just to calculate initial Nasmyth offset, to be transfered to NCS, to do latter the real pointing session with a good starting point). Getting pointing for Mars. |
