Notes.

(a)

See footnote of Table 110. The large telescope beams of the C86 and T89 surveys pointed toward Sgr B2(OH) include Sgr B2(M) (see Fig. 1 of Friedel et al. 2004).

(b)

The edges of the observed band are given in GHz. Since the band was not always fully covered, the effective bandwidth is given in parentheses.

(c)

Total number of detected lines.

(d)

Total number of identified lines.

(e)

Average number of detected lines per GHz.

(f)

Average number of identified lines per GHz.

(g)

Average number of unidentified lines per GHz.

(h)

Fraction of identified lines.
