SAM = SOAR Adaptive Module

SAM document navigator

Improved angular resolution at optical and infrared wavelengths

Uniform and selective compensation of low-altitude turbulence

A relatively wide field (3 arcminutes)

Image quality improved by a factor of ~2

Integrated CCD Imager

Correction achieved using a low-altitude Rayleigh laser guide star and two (or one) tip-tilt guide stars (R<18)

January 24, 2013. The paper based on SAM LGS data has been submitted to the Astronomical Journal.
Title: SOAR adaptive optics observations of the globular cluster NGC 6496
Authors: Luciano Fraga, Andrea Kunder, Andrei Tokovinin

January 18, 2013. Science verification of SAM starts this semester, 2013A. The deadline for the proposals is March 15, 2013. See the Call for Proposals

May 15, 2012. On the engineering night of May 8/9 SAM reached a resolutin of 0.26" in the I band, showing substantial gain over open-loop data. The image fragment (click to enlarge) shows globular cluster NGC 6496.

Filter I: exposure 120c, resolution 0.26" (closed-loop) and 0.51" (open loop).
