Global 3mm VLBI (GMVA)
-
GMVA projects are correlated at Bonn, using the DiFX software correlator. GMVA proposals are submitted using the NRAO Proposal Submission Tool (PST).
- Beginning semester 2016B phased ALMA may be requested as part of the GMVA. See the most recent Call for Proposals for how to request inclusion of ALMA in the array. Currently, the "B" semester (February proposal deadline) is the time to submit GMVA proposals requesting phased ALMA, since a VLBI proposal submitted to the GMVA must also be submitted to ALMA directly (ALMA proposal deadline is usually in April).
-
Submission deadlines: February 1, August 1, as for the VLBA/HSA, at 1700 Eastern Standard or Daylight Time.
