Ah. Obviously not. Understood now. Thanks a lot. See the result below.
The reverse gamma "IGAM00" works "a bit": takes much of time. I will have to find a better one.
(reverse gamma "IGAM00" is for the area positive x between 0.0001 and the minimum at approx 1.461)

Quote:LBL "IGAM00"

ASTO 06
XEQ "SOL"

in other area for example for x> 1.461 (see from page 27) there are more precise approximations
