Same as Fig. 24 for methanol, carbon monoxide, and ammonia. The vertical dotted lines indicate the times of the equinoxes (blue) and solstice (red). Only 25% of the mass of methanol and CO has been cumulatively lost at perihelion time. The emission of methanol does not decrease as quickly as for ammonia. The orbit-integrated mass losses at the last points are 66 ± 3, 25 ± 8, and 8.1 ± 0.2 × 10⁶ kg for CH₃OH, CO, and NH₃, respectively.
