Classification of molecules according to their sensitivity to the initial abundances.

Notes. [X]i,x and [X]f,x correspond, respectively, to the initial and final abundances for the set of initial abundances x (A or B). We consider the total gas and ice abundances. On the last row, some molecules are found with both [X]i = [X]f and [X]i ≠ [X]f. The category depends on the set of initial abundances. To differentiate them, we used a for set A and b for set B. NH3 and HNC (within brackets) have been moved to a different category, as their initial abundances differ by almost an order of magnitude.
