How does linmos calculate effective frequency?

Hi Mark, Jamie,
I'm wondering if you can tell me how linmos calculates effective frequency when you set options=frequency. If it helps, I'm making a large 25 deg^2 mosaic at 1-3 GHz (as you might know from my other ATCA forum posts).
And how do I interpret the flux densities in my image mosaic given the frequency mosaic, particularly for large bandwidths? Can the flux density detected at any given pixel in the image mosaic be interpreted as applying at the effective frequency as indicated by the same pixel in the frequency mosaic?
Cheers,
Andrew
