I am also working on this problem and have had some limited but not
complete success. If you can, please keep this thread running in the
channel so that others can follow along! 

I have completed various 
calculations based on flux measurements from various "bands" and 
converting this to mags/arcsecond, but I have not been able to derive 
successfully, the B parameter used in works like those if M.Covingtons book.

I would be most interested in collaboration in developing this 
concept further.

Best regards,
