No fringes to ASKAP. Reason unknown.

Zoom bands were used to incorporate ASKAP in the correlation. This results in a large amplitude error which is fixed by running 'ACCOR' in AIPS.

Analysis notes

Brief Data Summary

Scan listing

Plots of autocorrelations
Comments: Note large offsets from the nominal 1.0 value for autocorrelations due to scaling error when using zoom bands. Use of 'ACCOR' in AIPS will fix this (and the corresponding offset in the cross-correlation amplitudes).

Plots of uncalibrated amplitude and phase against frequency
Comments:

Plots of uncalibrated amplitude and phase against time
Comments:

Plots of cross-polarization amplitude and phase against frequency (not always available)
Comments:

Amplitude corrections from ACCOR
Comments: Note large corrections due to the use of zoom bands in correlation. ACCOR *must* be applied to get accurate amplitude estimates.
