Performance of ChAOS on the Apache Point Observatory's 3.5-m telescope

The Chicago Adaptive Optics System has been installed on the 3.5 meter ARC telescope at Apache Point for two years. Strehl improvements of 12 are obtained at 0.85 microns in 1- 2 arcsecond seeing. The major limitation in performance is set by the telescope vibrations.
