<p class="MsoNormal" style="margin-bottom:12.0pt">Dear Stefan:<br>
I also tried your data, and failed. Any values for the geom (first line in the 6S parameters) above 24 cause this error:<br>

If I put the igeom value at 24, and value for the wavelengthis above 164 (WV3 in the i.atcorr manpage) then the module segfaults.<br>
??<br>
<br>
Do I need a newer GRASS?<br>
