Observing

Observations

 

PI's of approved projects will get an email from the User Program asking to send Session Definition Files (SDFs) for their observations. Once the SDFs are received, they will be validated and then placed into the observing queue, and data will be taken as soon as possible.

To schedule your observations, the following pages will be useful to read:

• Currently known constraints and issues
• LWA Observational Status - technical information and capabilities
• How to prepare your Session Definition files (single-station)
• How to prepare your Interferometer Definition files (LWA Swarm)
• Submit your Session and Interferometer Definition files here
• Check the Submission/Validator queue here
• Watch your observations take place on the LWA operations screens
• The LWA Low Frequency Data Reduction Tutorial
• The LWA Single Baseline Observing Tutorial
