Notes. Stars of group 1 were taken from Noriega Crespo et al. (1997). All were observed by the IRAS satellite and two by the Spitzer-Glimpse program (†). The first column lists the Hipparcos number of the star; the second one, other identification(s). Column (3) shows the spectral classification, from the GOSC whenever possible or from NC97 otherwise. Columns (4) and (5) give information about MSX and WISE emission on the stellar fields, according to the following symbols.   : Point source on star,  ⊃ : bow shock candidate,  ⊃ ?: doubtful bow shock candidate, –: stellar field not covered by the survey,  × : no star or emission close-by,  ⊙ : extended source on star, •*: confusion with larger structure, φ: diffuse emission, •: emission excess, ○?: possible bubble. Column (6) lists the qualifiers (same meaning as before) as in the original work by NC97. [a] The star HD 36862, together with HD 36861 (O8III), belong to a rich cluster, are not single, and have a large spatial velocity. More than one feature can produce the surrounding IR emission detected. [b] Cappa et al. (2008) studied the environs of HD 92206, and identified an HII region. We discarded these two cases from our sample.
