Table 1: PN candidates in IC 10, Leo A and Sextans A. [O III]500.7 and H $\alpha$ +[N II] observed fluxes are given in units of 10^-16 erg cm^-2 s^-1. [O III] fluxes are corrected for the contribution of the companion oxygen line at 495.9 nm (see text). $R_{\rm corr}$ = [O III]/(H $\alpha$ +[N II]) is computed after correcting the fluxes for the reddening with E(B-V)=0.85 for IC 10, 0.015 for Sextans A, 0.02 for Leo A(vdB00), following Mathis' prescription (1990).
