Igor, Here is four tables for calculating MB and giving sigma. If you have some problem, give me the Bender table you already have and I could put the sigma value in it. If you send the IDL script for the Fig4, I could do the Faber-Jackson plot plus the new Fig 4. Let me know what do you prefer. Good Night.
