Targets of Opportunity

Mechanisms from Other Facilities

Facility/Telescope	Method	Pros	Cons
iPTF	CSV in e-mail	Easy to control manually	Feedback is slow, interface is ad hoc, monitoring status is difficult, web user interface is separate
LCOGT	REST interface	Powerful, simple to integrate with other pipelines, easy to control manually. Open source on GitHub!	Specialized for LCOGT telescopes

Scheduler feature requirements

• Submission
  • Program ID and sub-program/target name
  • List of fields & priorities
  • Cadence, filters, exposure time
• Management
  • Cancel entire sub-program
  • Modify list of fields, cadence, priorities, exposure time, filters
• Monitoring
  • List predicted observation timeline
  • List as-observed observation timeline
  • List all active sub-programs

Marshal feature requirements

• Ingest GCNs
• HEALPix-based spatial querying or annotation
• Visualize localization, fields, candidates
• Invoke optimal tiling and compare different plans with different assumptions about cadence, exposure time, etc.
• Manually edit observing plan
• Annotate and filter candidates according to numeric rubric (similar to Swift XRT scheme)
