Notes. Columns: (1) Name of the galaxy; systems are marked with the relative position to each other (e.g. N, S, E, W). (2) Classification based on radio spectral index maps and histograms. In parenthesis we give the histogram category. (3) Ratio of [Ne V] to the [Ne II] emission line: if the [Ne V] line is detected then the galaxy contains an AGN; if detection is an upper limit then it is a possible AGN; and if there is no high-resolution spectrum for the object, then we mark with “–”. (4) Ratio of the [O IV] to the [Ne II] emission line; if there is no high-resolution spectrum for the object, then we mark with “–”. (5) EW in microns of the 6.2 μm PAH feature. AGN or SB classification are based on empirical values as follows: values below 0.27 μm suggest the presence of an AGN; values above 0.54 μm denote a SB; and values in-between suggest the presence of both AGN and SB (see Stierwalt et al. 2013; Murphy et al. 2013). (6) Optical classification based on optical spectroscopy; reference is given in each case. For classification based on the BPT diagram (s stands for SLOAN data and r for RBGS data; Kim et al. 1995), SF stands for object in the star-forming region, COMP stands for objects between star-forming and AGN regions in the BPT (e.g. Kewley et al. 2001; Kauffmann et al. 2003; Kewley et al. 2006); Sey stands for Seyfert with subcategories 1, 1.5 and 2. References: “NED” for objects drawn from the NASA/IPAC Extragalactic Database (http://ned.ipac.caltech.edu); “BPT” from the BPT diagram; “M12” from Mazzarella et al. (2012); “V08” from Vega et al. (2008); “VX95” from Veilleux et al. (1995); (t) stands for reference for the galaxy system.
