The eclipses will have different shapes but you'll need good data to
see it clearly. A grazing EB eclipse will be more rounded and a
planetary eclipse will tend to have steeper ingress/egress and a
flatter bottom. I can generate examples of each if you'd like to see
them. Eclipse depths wouldn't vary with filters.
