Notes.
Luminosity and mass values taken from the literature have been scaled to the distance of D = 54.1 Mpc.
(1) NASA/IPAC Extragalactic Database (NED, http://nedwww.ipac.caltech.edu/), Luminosity Distance scaled to the reference frame defined by the 3K Microwave Background Radiation; (2) Izotov et al. (1999); (3) Reines et al. (2008); (4) Johnson et al. (2009); (5) in the entire SBS 0335−052 E region (Ekta et al. 2009); (6) Thuan & Izotov (1997a).
Obtained by considering an area of 0.2 kpc2, corresponding to
~
arcsec2.
This is a very conservative estimate, since the star formation takes place in the
two brightest SSCs, unresolved at an HST resolution of ~20 pc.
Obtained by integrating the SED model described in Sect. 3.
