Not sure if a database is needed to counter chromatic aberration.

i'm dusting off a few neurons here, but there are to my knowledge two types of chromatic aberrations--longitudinal and lateral. the former, requires specific knowledge of the glass to correct. the latter doesn't--well at least to correct most of it.

chromatic aberrations are most frequently found in optics that are hard to manage-- i.e. ultra-wide lenses, super telephotos, and high ratio zooms. i suspect a database relating to some co-efficent for these lenses could probably assist in some counter measure.

chromatic aberrations shouldn't be confused with purple fringing.
