Tests of the Observing Modes
Tests made on 20151021
On 20151021, the atmospheric conditions where poor (tau 225 GHz in the range 0.5-1.0), with fog. We were unable to obtain a proper focus, so we moved to test the observing modes. For this we used Jupiter + Ganymede with maps large enough normally to see both targets and check that the observing modes actually perform as expected. No skydip corrections where available at the time.
Observations where done between 04:24 and 06:16 UT.

nkotf_square
- Pako command: nkotf_square 10
Scan number: 20151021s24 et 20151021s25
- Note: The observation produced 2 scan files. The pipeline does not find Antenna imbfits for scan 25, so only scan 24 was reduced.
