ALMA footprint in Aladin

Posted by Thomas Boch on 17 October 2012 15:48 CEST

Since version 7.5, Aladin allows one to visualize the ALMA footprint and overlay it on astronomical images.
Since most ALMA images are expected to be mosaics, the user defines the ALMA band and a rectangular region on the sky which is filled with ALMA primary beams at the given frequency. Once created, the region can be interactively displaced and rotated and the individual pointing centers of the mosaic can be easily retrieved.
