Comment (by hinder):
I have checked the coefficients and they look correct. The only thing I don't understand is the convention for the dissipation strength. I don't get the 1/1024 factor (and by extension, the factors that appear in the existing orders). Do you have a reference for this? Is it a common convention? I compared with Gustafsson, Kreiss and Oliger (http://books.google.de/books?id=1JZ2mSQ- O6MC&lpg=PP1&ots=A9c4UBZBjl&dq=gustafsson+kreiss+oliger&pg=PA239&redir_esc=y#v=onepage&q=gustafsson%20kreiss%20oliger&f=false) top of p240 and when I compute that operator, I don't get the 1/1024 factor.
