Science Issues

• Relative performance comparisons.

• Performance predictions are as accurate as can
  be made.

• Breadth of science capability?

• Availability of AO guide stars?

• Availability of laser guide stars?

• Detector performance vs science capability?

Guide Star Requirements

• ALTAIR natural guide star system.

• Optical AO guide star R lt 15 mag within 20".

• Near-infrared OIWFS guide star R lt 20(?) mag
  within 120".

• ALTAIR laser guide star system.

• Optical AO guide star R lt 17-19 mag within 30".

• Near-infrared OIWFS guide star R lt 20(?) mag
  within 120".

Or

• Near-infrared OIWFS guide star R lt 15(?) mag
  within 30".
