Notes. The SEDs were fitted with Le Phare by assuming a Calzetti dust-attenuation law and a Chabrier IMF. For details, see Sect. 4.2.2.

(a)

Spectroscopic redshift.

(b)

The SED blueward of the Balmer break is poorly sampled, resulting in a not well-constrained photo-z of (99% c.l.). The only strong emission line falling in that redshift interval is Hα at z = 0.283. The reported galaxy properties were obtained for that redshift.

(c)

Photometric redshift.

(d)

Projected distances are measured from the optical transient to the galaxies. The projected distance of G3 assumes z = 0.66.

(e)

“n.o.f.” denotes the number of filters.
