I think here are all the necessary changes are done as
manual. Then i plot case.sigmak for optical plot and
plot is not matches with published fig. I checked the
calculation very well but i can not what is the wrong here. <br>
<br>
<br>
I have another question why we write atom no 0 in the case.inso files . <br>
<br>
<br>
Any kind of suggestion regarding this problem highly appreciated.<br>
<br>
<br>
With best regards,<br>
