Fringing in the images taken with EFOSC

The fringing pattern:

This page contains fringing pattern for EFOSC2 through the filter i#705. The image has been created the following way: So far we do not know how variable the pattern is. The intensity varies a lot, but the shape seems to be quite stable. We plan to do more measurements in the next future to clarify this point.

How to correct for fringing?

Fringing is an additive pattern, hence it has to be subtracted from the images after the pattern has been scaled to the actual value of the fringing in the image.
