[Night shift: Juan & Samuel]

Observations with DAQV3 old parameters. Mostly 199-16 (GT_LP SZ) and 122-16 (GT-LP GASTON), plus some additional nikaw18 for completing V3 checklist.

[Morning shift: Alessia & Isabelle]

6h40 UTC: change to DAQV1 with new parameters. From scan #75 on.

[Afternoon shift: Bilal & Stefano] We switch to new parameter file for A1 and A3. Did 3 beammap and switch back to the old parameter until full treatment of the beammaps.

Meanwhile Juan - with some help by Stefano - solves two long-standing issues: now v3 imbfits contain the sweep frequencies and the signal is positive.

Weather conditions were unstable at the beginning of the night. We mainly concentrated in project 193-18.
