InterferometryDiscussionGroup 2011-2012

This is the page for the 2011-2012 IDG. To see the page for the 2010-2011 academic year, see: 2010-2011 IDG

Meetings: Tuesdays from 10:00 - 11:00 in ER 230.

The purpose of this group is to discuss the basics, and sometimes the intricacies, of radio interferometry. The discussions are informal and are led by volunteers depending on the topic of the day.

Contact Scott Schnee (sschnee at nrao.edu) to suggest a topic for discussion, to volunteer to lead a discussion, or to be added to the email reminder list.

Next Meeting:

March 13 - Gibbs ringing and Hanning Smoothing - Amy Kimball
