Note: To support our ongoing RFI monitoring efforts, any feedback from your
program on RFI can be sent to: [email protected]
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:

13. hifv_finalcals:

Final amp vs time gain solutions, spread in ea18, as noted by staff. Need to flag these data.

19. hif_makeimages (cals):

Peak intensity of the phase calibrator image (J1744) is 0.465 Jy/beam, consistent with the derived flux of 0.476 Jy.
