Analysis notes

General comments: Correlation was done using 8 MHz subbands (use of “zoom bands” smaller than “parent bands” is required when different telescopes record different bandwidths).

Tid recorded an inverted band; the fix to this in correlation means that alternate empty subbands are created (i.e. there are twice as many subbands/AIPS IFs as expected, but only the odd-numbered IFs contain data).
Tid observed with two antennas at the start and end, respectively:
TD = DSS34
TI = DSS45

Ceduna maser/phase stability problem has been fixed!

ATCA has a fairly large delay offset between frequencies (~0.1 mus), but data should be OK after fringe-fitting.
