Summary

idac ñ Successfully applied for object and PSF recovery from AO data.

- Caveat ñ Forward modeling of the imaging process is necessary for obtaining

good photometry. This includes flat-fielding and background subtraction.

ñ Future developments

Symmetry Breaking

- Pupil Constraint (PSF is power spectrum of complex pupil)

incorporate psfcal into idac

- Object Modeling

Multiple Point source field - _ Ai _(x-xi,y-yi)

Asteroid ellipsoidal figure

Noise Regularization

- Autocorrelation Function metric ñ looks at structure of residuals

EACF = _ik ACF2[gik ñ (f 'i * h'ik)]

- Object regularization

Pixon based schemes

object smoothing - f 'i = _ 2 * k
