Predicted values of the age, mass, stellar and nebular extinctions, fraction of ionizing photons absorbed by dust, emission fluxes and luminosities and EW(Hβ) of the starburst (STB) in IRAS 0833, assuming the UV fluxes from HST/ACS and IUE and the average value of both.

Notes. The Galactic extinction effect has been removed from the E(B − V) values, which thus strictly correspond to the intrinsic extinction within the source. Contribution to the optical continuum by old stars was considered when estimating EW(Hβ) (see Sect. 3.5 for details). Observed values are also shown.
