Tour of the Facilities

First Science with the Parkes 13mm receiver

First Observation• New detection of H2O Maser.• Observation carried out by Jose-Francisco Gomez and his P616 team.

First science with the new 13mm receiver was the detection of a new post-asymptotic giant branch star, a very rare and short-lived class of object. Data provided courtesy of Jose-Francisco Gomez et al. Plot prepared by Stacey Mader.

Observations of a strong Ammonia source, G316.819 showing strong (1,1) and (2,2) transitions.

Removing baseline ripple

The plot shows two observations taken one after the other, the first (upper panel) with no special 'de-rippling' measures, the lower taken in a mode where the receiver is moved cyclically up and down to 'smear out' the ripple.In the observation for the lower plot the receiver was moved up and down in time with a sawtooth pattern, with amplitude 6.3mm peak-to-peak (lambda/2) and period 60 seconds. Integrations were 4 minutes (exact multiple of 60 seconds).

Experiment carried out and data provided by John Reynolds.
