Targets of Opportunity

Mechanisms from Other Facilities

Facility/Telescope <-- -->	Method	Pros	Cons
LCOGT	REST interface	Powerful, simple to integrate with other pipelines, easy to control manually. Open source on GitHub!	Specialized for LCOGT telescopes
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

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)
