ATNF VLBI Wiki

Recording to UTAS V001B.

Using DAS profile vsop.pro.

Start experiment in good weather, and with all five track antenna in the tied array.

Reference antenna is CA01 on W104.

Re-tied at 01:02 UTC

Duriong this 1934-638 scan, from 01:07 to 01:17 phases vary by >100 degrees between ca01,2,3 and ca04,5, before returning to within ~60 degrees of each other. Will drop ca04,5 from tied array if this continues. Seemon path noise is 200~250 microns, but likely to worsen as day goes on.

01:23, at start of next scan (1039-474) phases to ca04,5 out by 90 degrees again, so drop from tied array (tie ant 123 123, tie gain 0.2 0.2)

07:29 phase up again, during 1903-802 scan
