COMMENTS AND OUTAGES

Outage information format: Start Time, End Time, Category, Form#, # Antennas, Down Time(minutes) Antenna ID(s) and Data Effect Description

Number of Antennas Used: 27

10Mar 11:04:30 Starting project 22B-193.

10Mar 11:04:30 The band(s) used is(are): X K.

10Mar 11:04:31 On source 1331+305 with all available antennas.

10Mar 11:04:30 Antenna(s):28 do not have good baseline positions determined for them because they were moved to their present location recently. Please check for any significant errors and submit them to the NRAO Helpdesk (https://science.nrao.edu/observing/helpdesk) under the VLA Observing department.

10Mar 11:04:30 Note: To support our ongoing RFI monitoring efforts, any feedback from your program on RFI can be sent to: nrao-rfi@nrao.edu The key information to provide is:

• Observation/project code
• Frequency and Time of the observations
• The characteristics of the RFI signal, in particular if it is continuous or intermittent?
• If possible, a spectrum of the RFI should be included in the e-mail. Thanks very much for your support; this information will be continuously updated on the EVLA science pages at: https://science.nrao.edu/facilities/vla/docs/manuals/obsguide/modes/rfi/

Issues noted but not flagged by staff:

• ea28 had a pointing error that caused low gain amplitudes.
• Major issues automatically flagged by the pipeline:
• ea27 A0C0 was flagged for a DTS hardware issue and B0D0 was flagged for a hardware issue.
