Abstract

Stereo scintillation detection and ranging (S-SCIDAR) is a development of the well-established SCIDAR turbulence profiling technique. An S-SCIDAR instrument has been installed at the focus of one of the 1.8m Auxiliary Telescopes at Paranal observatory since April 2016. We discuss the limitations imposed by the Paranal S-SCIDAR instrument’s finite pixel size and exposure time. We present Monte Carlo simulation results quantifying the errors due to finite spatial and temporal sampling. We have reprocessed the existing S-SCIDAR dataset to compensate for these error sources; we discuss the impact of these corrections on the measured turbulence statistics.
