Correlation notes

ATCA reference station is W104 (CA04)

S-band continuum experiment. PI Paula Benaglia, contact author Sean Dougherty.

Correlation: 128 spectral channels per IF, 2 sec integration, included crosshand polarizations.

Most stations started a bit late. Parkes had wrong frequency setup for first hour. Hobart started recording at UT 3:04.

Hobart and Ceduna recorded first two subbands only.

Output file: v191b.rpf

Data verified by: Claire Date: 6th April 2009

Comments: Hobart bandpasses exhibit apparent severe interference - strangely peaked autocorrelations, particularly in LHC. ATCA known spikes at band edges (tied array?). Ceduna bandpasses not always flat.

From VPLOT uncalibrated plots we see CA is off-source for a short time at the start of the experiment, Hobart takes longer to come on (Mopra may be slow too). Ceduna data is no good for almost half the experiment. Parkes comes online late but the source (and most calibrators) set very early.

As expected then, POSSM uncalibrated plots show lots of rubbish to Ceduna and Parkes, Ceduna more or less throughout the entire experiment.
