Designing an experiment

Laing with Heywood, Kloeckner, Etoka, Perley

  • Writing a good science case
    • Clear objectives (test some idea; identify an object in a new band; ...)
  • Basics
    • Frequency - particular spectral line(s); considerations affecting choice of continuum band (spectrum; variation of polarization with frequency).
    • Spatial resolution and maximum scale of structure. Wide-field issues (primary beam; need for mosaic; confusing sources)
    • Spectral configuration (one or more lines; resolution; continuum; ...)
    • Working out the surface brightness
    • Where can relevant archive data be found?
  • Choice of instrument
    • Which instrument(s)/configuration(s) are needed?
    • Single-dish data needed?
    • How much time?
    • Adequate coverage and signal to noise ratio?
    • Measurement accuracy?
  • Other issues for the technical justification
  • Calibration strategy
    • is self-calibration possible;
    • how important is good astrometry?
  • Timing constraints and conditions?
    • Observations simultaneous on different instruments?
    • Good observing conditions needed?
  • Proposal tools and where to find them
