Number of Antennas Used: 27

23Mar 10:05:26 Starting project 22B-193.

23Mar 10:05:26 The band(s) used is(are): X K.

23Mar 10:05:27 On source 1331+305 with all available antennas.

23Mar 10:05:26 Antenna(s):28 have recently updated baseline parameters to correct for errors resulting from their recent relocation. Please check for any significant errors and submit them to the NRAO Helpdesk (https://science.nrao.edu/observing/helpdesk) under the VLA Observing department.

23Mar 10:05:26 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.

23Mar 10:05:26 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/
