Spectral Line Observing Modes

Scope

Description: The spectral line observing mode commissioning covers the testing, development and documentation of observing strategies and post-processing guidelines for spectral line observations. Information and participation in the band-based groups (for additional guidelines) is expected to be reflected in the recommendations.

Group

• Leader: Goss/Ott
• Primary Participants: Carilli, Chandler, Claussen, Dhawan, McMullin, Momjian, Rupen, Sjouwerman, Wrobel
• RSRO Participants: Aravena, Brogan, Corder, Chomiuk, Hunter, Linz, van Gorkom
