12Feb 13:38:06 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:

• There is gain compression evident in the observation.
• Antennas ea09 (A1C1) and ea25 have hardware issues.
• Spw 10 from ea15 has low amplitude in the complex gain calibrator's UVwave plot.
