Single star Cn2 Profiler

MASS: Multi Aperture Scintillation Sensor

The new technique proposed by A. Tokovinin (now with CTIO, Chile) is developed by V. Kornilov (Sternberg Institute, Moscow) under contract with ESO, in the frame of the VLT Adaptive Optics Program. Check updates on A. Tokovinin's web page.

MASS-LITE, a step towards automation

A light version of MASS using a 10cm diameter refractor was designed at Sternberg institute to be installed piggy-back on the ESO DIMMs and thus benefit of their automation. The system was first tested at La Silla before starting operation at Paranal.
