Please check for any significant errors and let the Data Analysts (email - analysts@nrao.edu) know what you find. Thank you. 09Feb 19:53:30 As part of the EVLA transition plan, a new correlator controller has replaced vintage equipment and is now routinely in use. The system has been thoroughly tested but we welcome reports of problems that may be related to improper correlator behavior to analysts@nrao.edu. 09Feb 19:53:30 We are currently including all checked-out (operational) EVLA antennas in the VLA by default. For your project, we have included the following EVLA antennas in the array: 13 14 16 17 18 23 24 26 09Feb 19:53:30 Please note that using the EVLA antennas is a shared-risk operation and we cannot guarantee that useful data will be produced by these antennas. Users should consult the web page http://www.vla.nrao.edu/astro/guides/evlareturn for known problems and workarounds in using the EVLA antennas with the VLA. We would like your input and feedback on the use of the EVLA antennas in your project; please send all comments and/or questions to gvanmoor@aoc.nrao.edu. 09Feb 19:53:30 09Feb 20:17:00 Software 8.00 188.0 Antenna(s) 13 14 16 17 18 23 24 26 (Data: Lost): EVLA Some difficulty with submitting script, fell back on using obs2py 09Feb 20:58:00 Antennas 14 18 24 removed from analog sum at observer's request (take) 09Feb 22:58:00 Your new operator(s) is(are): David Midgett 10Feb 0:03:00 Inspected the VLB instrumentation.
