Notes. (a): The listed transitions consist of the quantum configuration as given in the LAMDA files: JKa,Kc${J_{{K_a},{K_c}}}$ for SO2, JK for CH3OH, and JKp,Ko${J_{{K_p},{K_o}}}$ for H2CO.

(b): The beam sizes for the SO2 and CH3OH transitions are on the order of 0.33″×0.26″, whereas those for H2CO are on the order of 0.48″×0.38″.
