Notes. See Table 2 for spectral window parameters.

^(a)

We use the notation of Peterson et al. (2011) for all sources except IRS5A, IRS5N, and SMM 2, for which we use the notation of Lindberg & Jørgensen (2012) and Lindberg et al. (2014b). These are referred to as CrA-19, CrA-20, and CrA-43, respectively, by Peterson et al. (2011).

^(b)

Assigned from the spectral index α (Peterson et al. 2011). Class I sources are Class I or younger.

^(c)

Only partially covered by the IRS7B line survey. The observations do not cover 216.1–217.2 GHz, and the 217.2–217.9 GHz portion is covered only at a lower S/N level (37 mK (km s^-1)^-1).

^(d)

Also known as IRAS 32.
