^(a)

Calculated following Kennicutt (1998).

^(b)

Calculated following Calzetti (2012) assuming a Kroupa (2001) initial mass function, stellar masses in the range of 0.1 M_⊙ < M < 100 M_⊙, continuous star formation lasting for τ ≥ 6 Myr with a temperature of T_e = 10⁴ K and an electron density of n_e = 100 cm^-3.

^(c)

Calculated from [O iii]/Hβ.

^(d)

Calculated from [N ii]/Hα.

^(e)

Calculated from O3N2.

^(f)

Zero extinction has been assumed.

^(g)

Aperture has been centered on brightest Hα spaxel.
