Transient/Variable Sources


Targets of opportunity

  • Known transient sources
  • Unknown transient sources
  • TOO policies & responses at different instruments
    • pre-approved allocations
    • balancing time requested against science requirements.
    • multiple requests from different groups
  • Observing considerations
    • consistent phase calibrators
    • variable structure vs variable uv coverage
    • brightness variations over observing windows (see practical session)
  • Specifying observing settings e.g VLA dynamic scheduling
  • Expect the unexpected?
  • Examples will be discussed
