Snapcurves – P80016
• Suppose you don’t have stability on long (day) timescales, but you think you have a well characterized instrument.
• Or you don’t want to observe an entire phase
• Or can’t observe an entire phase.
Is it possible to recover a phase curve with random snapshot
observations?

ChallengesGain as a function of position & undersampling
Pmap data which is not the observation itself
Residual non-linearity
Is randomly observing possible?
Assumes no changes in phase curve between phases
