Abstract
Weak space fringes mop-hobart is low, based on J2148+06: Baseline error?

Only 32 channels in the uv data. With delays of ~ 300 nsec this should just be okay... however I do have trouble making sense of the data.

Comments on Difmap processing
Only 32 channels, but with the delays found there would be signal loss. Should be recorrelated.
