Hi Radek,

Good news is that I can reproduce the last step "hook" -- will let you know as soon as I have a fix.

The hook remains there for all the parameters I tried, sometimes it is smaller, sometimes it is very large. How can I get rid of it?

Fortunately, these are for both A09 and A09p, but none of the mixes can be used consistently. Has anyone played with low-temperature opacity tables with A09 and can share the tables? Now it seems that only with gn93/gs98 and OPAL the fully consistent calculations can be done (ie., we have gn93/gs98 for high temperature, low temperature and type-2 OPAL opacities).
