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.

Pointing towards Mars. We are using the geometry reduced from yesterday's observation (kidpar_20151015s154_155_156_noskydip.fits) |

Checking pointing. Problem: All subscans set to 0. But the sze of the file is correct. |

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. |

Axis=Z. At 1mm: z=-0.028+/-0.009. At 2mm: z=0.058+/-0.042. Close enough, keeping focus Z=0.0 |
