Please check for any significant errors and let the Data Analysts (email - analysts@nrao.edu) know what you find. Thank you. 03Dec 18:51:00 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. 03Dec 18:51:00 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 18 24 26 03Dec 18:51:00 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. 03Dec 18:51:00 04Dec 09:16:00 T100416 1.00 865.0 Antenna 23 (Data: Lost): EVLA Antenna is being used for EVLA testing 03Dec 18:51:00 03Dec 19:10:00 Other 6.00 114.0 Antenna(s) 13 14 16 18 24 26 (Data: Lost): EVLA EVLA portion of file did not start properly.
