The above plot shows the performance (Strehl at 2.2 microns) of the AO system using natural guide stars of various magnitudes. For stars brighter then ~10th mR the system is limited by calibration error, significant Strehl can be achieved on stars as dim as 14thmR. The model predictions are from first order analytical equations. The model prediction is not a fit to the data, but just the predicted performance given the system parameters, measured r0 and measured calibration errors. The excellent agreement is a demonstration of our understanding of the AO system error terms.
