Hi Stefan,
Sorry I don't think I cc'd the mailing list last time. Looking through
continua.cc I can't seem to find anything for CKDMT252, do you mean CKDMT24
instead? The options for continua given in the documentation are listed at the
bottom of this message, however some of them, aren't in the continua.cc file,
so I get an error. I have a separate question regarding the self and foreign
continua, would you advise using both in a radiance calculation to include both
types of continua behaviour, such as in the code snippet below?
Q.ABS_SPECIES(2).TAG{1} = 'H2O'
Q.ABS_SPECIES(2).TAG{2} = H2O_SelfContCKD24;
Q.ABS_SPECIES(2).TAG{3} = H2O_ForeignContCKD24;
Thanks very much,
Emma

Dear Emma,
sorry for the slow reply, I’m very overloaded. Writing to the mailing list will
usually be faster.
Just look in file continua.cc after all tagnames that contain CKDMT252. They
should work out of the box, otherwise please let us know.
Best regards,
Stefan
