Service Documentation

Emulsion and Filter

Most plates had a Kodak 103a-O emulsion, exposed through a WG-2 filter.

One pair per field was taken each month on Kodak 103a-D emulsion, using a Y-6 filter.

Best effort is made in determining emulsion and filter; metadata regarding those values are incomplete.
