Notes. The identification numbers are followed by celestial coordinates, instrument, EW(CO)s, spectral types, Teff , H2O indexes, and comments.

(+)

Temperature erros account for accuracy in spectral types of ± 2.

(a)

This Asymptotic giant branch stars (AGB) coincides with the maser OH22.77−0.26 (Blommaert et al. 1994). The stellar velocity (LSR) is 93.1 km s-1.

(c)

XMM point source number 5 in Table 1 of Mukherjee et al. (2009).

(d)

BG = object in the background of the cloud.
