Diffuser-Assisted Time Series Exoplanet Photometry with ARCTIC

ARCTIC has been a workhorse in the field of exoplanet followup photometry, contributing to several recent discoveries. The instrument’s remarkable diffuser element, which broadens the source PSF into a wide, tophat-like profile, has pushed ground-based photometry to sub-millimagnitude precision. We...

Description
Summary:ARCTIC has been a workhorse in the field of exoplanet followup photometry, contributing to several recent discoveries. The instrument’s remarkable diffuser element, which broadens the source PSF into a wide, tophat-like profile, has pushed ground-based photometry to sub-millimagnitude precision. We summarize the instrument’s noise performance, show a fitted transit light curve, and offer our best observing practices for future observations.
