hi emma, which arts version are you using? arts-2.2 has ckdmt250 listed. that's the one stefan was talking about (obviously i didn't fix the wrong version number yet. will do in the next days, renaming them to ckdmt252. but so far you find them as ckdmt250). if it's not in your arts-2.2 distribution, please update your arts. we fixed a number of bugs during the last year...
