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:

QA Summary:

• ea02, ea07, ea15, ea27 are all flagged in "By Topic" Flagging Summary in the fields

Stage 13 Plots (these are antenna based solutions)

Bp Initial Gain Phase Plots

Most plots look like this one:

But ea22 isn't flattened out completely:

Final Amp Time Cal Plots

Antennae ea04, ea09, ea12, ea18 all exhibit odd behavior:

Final Amp Freq Cal Plots

The same antennae in frequency (ea04, ea09, ea12, ea18):

Final Phase Gain Cal Plots

Many of the plots decrease like ea11:

Stage 17 Plots

there is some scatter, but not much:

the fields of the CMZ have a really large spread in terms of amplitude. This plot has one of the highest amplitudes at about 1:

this field has one of the lowest amps at 0.07:
