Number of Antennas Used: 27

08Mar 13:09:24 Starting project 22B-193.

08Mar 13:09:24 The band(s) used is(are): X K.

08Mar 13:11:58 On source 1331+305=3C286 with all available antennas.

08Mar 13:09:24 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.

08Mar 13:09:24 To access your data from the NRAO archive visit: https://science.nrao.edu/facilities/vla/archive All VLA science data are processed through the VLA calibration pipeline.

08Mar 13:09:24 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/
