27Jan 14:49:31 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 in pipeline run

• There is gain compression evident in the observation.
• Antenna ea09, ea18, and ea25 have hardware issues.
• The low points in the bandpass and complex gain calibrator UVwave plots are from ea15, spw 10.
• Baseline ea25&ea26, spw 9 is also causing some low amplitude points in the complex gain calibrator's UVwave plot.
