SPECIFY [*|Buffer|FileName.Type] TELESCOPE Name Add or Replace the telescope section with the parameters (name, size, posi- tion) for the specified telescope name, essentially to get the most appro- priate beam parameter. A Telescope section is required for MOSAIC. The beamsize will depend on telescope diameter and frequency, with a telescope dependent factor. The de- fault beam size is 1.13 Lambda/D.
