Interface with the telescope: PaKo

Short manual on useful "Pako for Nika" see on Granada computers on the NIKA directory Pako_helpv17.txt

- Pako scripts are in the Pako subdirectory

- Before starting the pointing session, we may be requested to move the azimuth by 60deg to reset the inclinometer of the az axis.

- Always stay at more that 1 deg from the Sun. There are internal safeties that prevent the antenna to point to the Sun, but we may not get error messages.

- try to get sources uniformly distributed on the sky, hence give priority to high elevation sources that are usually harder to reach.

- Do one focus at the beginning. No need to do more focus than one every 2-3hours.

The antenna can point between 60 and 460 degrees in azimuth, between 20 and 80 degrees in elevation.

- If a source is available both at low and high azimuth, use command SET TOPO LOW (or SET TOPO HIGH) to stay on the source without moving.

- The minimum number of sources to observe for the pointing model is 15. 30 is good enough.

- the pointing sources should be observed on 'short' period, e.g. 3-4 hours to avoid daily pointing variations
