Joint VLA/VLBA/GBT Proposals
Modified on Thursday, 21-Jan-2010 11:24:50 MST by Mark Claussen
- Proposals requesting multiple NRAO telescopes (VLA, VLBA, GBT) are considered
joint proposals unless they are pure VLBI proposals in which the GBT, phased
VLA ("Y27"), and/or a single VLA antenna ("Y1") are requested as part of a VLBI array.
In general, joint proposals must be submitted as separate proposals
to all telescopes requested. The Proposal Submission Tool (PST) is required for joint proposals
using the VLA, VLBA, and the GBT; beginning at the 1 October deadline, VLBA/HSA proposals
must be submitted using the PST .
Joint proposals should include the same scientific and technical justifications.
- An exception to this policy is the use of the VLA for finding calibration sources, for
polarization calibration, or pulsar phase determination in support of a VLBA proposal. In these
cases, VLA time can be requested directly from the VLBA proposal.
For VLBA proposals (which must use the PST), VLA observations
for this purpose should be requested in the text of the proposal. Justification for the use of the VLA for
this purpose should be included in the Scientific or Technical sections of the proposal.
Similarly, for VLBI proposals that wish to include the GBT, phased VLA ("Y27"), and/or a
single VLA antenna ("Y1") as elements of the VLBI array, select them from the "Stations" list under
Resources in the PST, and include the appropriate reasoning in the justification
regarding the need for the GBT and/or one or all of the VLA antennas.
