In my new research study I need the character tables of a simple group $^2D_8(2)$ and for that I was trying to find a reference and in this regard I came across a reference "Character degrees and their multiplicities for some groups of Lie type of rank < 9" with the link address "http://www.math.rwth-aachen.de/~Frank.Luebeck/chev/DegMult/index.html?LANG=en"»Frank.Luebeck/Chev/DegMult, 2005". Unfortunately, I could not find the character degrees of the group in that reference.
I sent an email to the author, but I have not received an answer from him, yet. I wonder if you can help me to find out the irreducible character degrees of $^2D_8(2)$. Can you give me a reference for finding the degrees of irreducible characters of $^2D_8(2)$?
I would really appreciate your help.
