Early Science Operations: Concepts
In 2007:
• Staff hired into/trained by Integration and
Commissioning teams
• Not 24/7 science operations
• Limited array configurations
• No breakpoints, limited eavesdropping
• No imaging pipeline
• Central archive at OSF
• Only two (2) proposal calls in first 24 months
• Other issues, see Plan
