Notes.
These objects are galaxies within compact groups of galaxies or are parts of other galaxies. The metallicity quoted here is the mean value for the group of objects. For Mrk 1089, the group is composed of regions A−C, B, E, F1, F2, H from López-Sánchez et al. (2004). For UM 311, the group is composed of regions 1−2−3 of Moles et al. (1994) plus NGC 450 and UGC 807. For HS 0052+2536 the group is composed of HS 0052+2536 and HS 0052+2537. For all of the objects, the “group” corresponds to the objects included in the aperture used for the photometry (see Sect. 3.1.1). For the metallicity of the object only, see Madden et al. (2013).
