Hi Patrick, Apologies for my ignorance but what is the more general qarts system? Does that mean applying the below code snippet in the arts C++ code?

And we prefer if all questions go to any of the arts and qpack lists. The answer is: [y,y_aux] = arts_y( Q ); There is now way to obtain the aux vars by qpack2. If you want this information you must use the more general qarts system, where then arts_y is the function to use. Or, of course, using arts directly.
