Notes. (1) Cluster name; (2) half-light radius and; (3) tidal radius of the King-model cluster fit from the catalogue of McLaughlin & van der Marel (2005); (4) K-band integrated magnitude within the tidal radius from Pessev et al. (2006). For NGC 1806, where r_t is unknown, we list the magnitude within 200 $\hbox {$^{\prime \prime }$ }$ radius. The same applies for NGC 2173, because aperture equal to the tidal radius does not exist; (5) K-band magnitude from Pessev et al. (2006) with aperture radius 20 $\hbox {$^{\prime \prime }$ }$ , which matches reasonably well our central SINFONI mosaics; (6) sampled bolometric luminosity within the clusters central mosaics in $L_{\hbox{$\odot$ }}$ , computed following Eq. (1); (7) integration radius, to which we have added stars from the additional bright AGB star sample; (8), (9) and (10) photometry with the fixed aperture radius of 90 $\hbox {$^{\prime \prime }$ }$ of Mucciarelli et al. (2006).
