[Wien] Mstar output result

[uchit chaudhary]

Dear Dr. Rubel,

I computed the effective mass of GaAs, but I did not get the result as
mentioned in the article. Moreover, I did calculation in two ways 1. Just
with x lapw1 and x lapwso 2. By generating kpath L-Gamma-X for 100 points
(x lapw1 -band and x lapso). I found the results are different. What is the
difference between the two calculations? Are they the same?  Do they affect
effective mass?

I may not understand or read the output results correctly. So please
explain about the output to read. In the article it is written that 13 k
points mean gamma point. How to know which k points mean which high
symmetry point? In the case of an indirect band gap, VBM is at Gamma and
CBM is at X. How to search for results in the output file in such a case?
Please explain in detail about extracting data from output files.

Thank you for your time.

Best regards,
Uchit
