Beammap sequences, which are focus + pointing + beammap, are to be done at least once a day, spanning various elevation, at the best average focus (z central - 0.2 mm). If the weather conditions are good enough, lateral focus corrections can be implemented as well, using the maps of the residual after subtraction of a Gaussian beam. |

Pointing checks
The pointing model is to be checked on the first night of the campaign by means of a mini pointing session (about 10 sources), and if needed a complete session (minimum 15 sources, 30 is better). [Add here a summary of the pointing session(s)]
Beammaps
Beammap sequences, which are focus + pointing + beammap, are to be done at least once a day, spanning various elevation, at the best average focus (z central - 0.2 mm). If the weather conditions are good enough, lateral focus corrections can be implemented as well, using the maps of the residual after subtraction of a Gaussian beam.
Beammap analysis status
The table below gathers the beammap scan ID, comments related either to the observing condition or to the reduced beammap quality and the analysis status
Status "done" means the analysis is completed, namely the kidpar file is produced using a 2-step iteration analysis, and uploaded in SVN.

Special beammap sequences
* For the optimization of the best average focus, a few series of beammaps at different axial focus in a row are needed: the focus settings to be spanned are z0 - 0.2mm, z0 - 0.3mm and z0 - 0.4mm. * For the study of the elevation impact and the test of destriping methods, couples of beammap with orthogonal scanning startegy will be made (using @beammap99.. a (default) and e (along the elevation)).
Opacity
A skydip scan per 8-hour observation shift, in all possible weather conditions, is needed
