Ray,
The ultimate weighting tool is to leave the worst subs out of the integration, but PI also has a script (SubframeSelector) which allows you to calculate a weighting for each sub based on a collection of parameters including FWHM, Eccentricity and SNR. This script adds a weight value to the FITS header that is used during image integration.
Cheers,
Rick.
