Abstract
space fringes. High space rate. Mopra low again! Flux agrees with light curve.

EBF: 09-OCT-2005

Put data in aips. Increased MP by 5.0, seems to fit. new data in J0253-54.UVF

Two component fit to define fine-scale structure. An elliptical gaussian is not as good a fit.

Comments on Difmap processing
Morpra seems to be low again, by 4.35.

Gaussian fit is adequate solution.
