EVLA transition for Observers
Added 01/11/2010: With the January 11, 2010 VLA correlator shut-down this page has become obsolete and will not be maintained any further. For EVLA observing using the new WIDAR correlator please refer to the new EVLA page.
This is a redesigned Web page. The old Web page was frozen January 2, 2008 and is available here.

While the NRAO is in the process of building the EVLA, retrofitted antennas are being returned to the operational VLA, and are operated in a transition mode that may not yet have all VLA features available. Detailed information about the inclusion of EVLA antennas into the VLA is posted at the links below and updated on a regular basis.

All EVLA antennas accepted by Operations will be included in your observation - no special comments are needed in the observe file. We recommend that observe files are sent to the data analysts for checking well in advance of observing.

For any questions about using the EVLA send an e-mail to vlahelp, and one of our support scientists will get back to you.
