GMVA call for proposals
The 40m radiotelescope is part of the Global Millimeter VLBA array and takes part in two seasons per year in Spring and Autumn. ALMA takes part in the GMVA observations of the Spring session. Each session usually lasts seven days.
The GMVA observes at 86 GHz. The 40 m RT has a dual polarization receiver with a very broad band: 72-90 GHz.
