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.
ATCA
• Installation of interim CABB system continuing• Shutdown March/April 2009 for full CABB installation• Upgraded seeing monitor installed• NASA tracking continuing, at lower level than nominal 10 hr/wk• ATCA calibration (esp. in mm bands) being addressed• Poor image rejection in parts of mm bands being understood• Synthesis School held 29 Sep to 03 Oct • New Systems Scientist, Jamie Stevens, to start in January
• Who do I call?• Support can be requested at time of proposal
• Support during the day from local staff
• After hours support provided by DA
Synthesis Imaging School 2008
