GSAOI is described in detail on the GSAOI web page.

The camera has an 85" x 85" field-of-view with a plate scale of 0.02" per pixel.

The filters are divided into broad- and narrow-band, in order of increasing wavelength.

The detector read mode sets the read noise at the expense of longer readout overheads.

GSAOI must use Canopus as the wavefront sensor.

The Strehl ratio is estimated from the selected filter and image quality:

IQ J H K
20%-tile 10% 15% 30%
70%-tile 5% 10% 15%
85%-tile 2% 5% 10%
