Notes. (a)a(b)=a×10b. (b)Sakai et al. (2009a). (c)Benson et al. (1998). (d)Hirota et al. (2009). (e)Jørgensen et al. (2004). (f)Jørgensen et al. (2002). (g)Tafalla et al. (2000). (h)Agúndez et al. (2015). (i)Bold type indicates model results deviate from the observations by one order of magnitude or more. (j)l-C3H2 and c-C3H2 are isomers but they are not distinguished in the reaction network. The results represent the sum of the abundances of l-C3H2 and c-C3H2. So far only l-C3H2 is observed toward L483. (k)This number is 0 based on model results. However, it should be interpreted as a number below 10−13.
