New methods for ALMA angular-scale based observation scheduling, quality assessment, and beam shaping

Dirk Petry, María Díaz Trigo, Rüdiger Kneissl +2

Up to now, the completion of an ALMA interferometric observation is determined based on the achievement of a given shape and size of the synthesized beam and the noise RMS in the r…
