\caption{Physical parameters and abundances for \ion{H}{ii}~regions in
the dIrrs of the Sculptor and M~81 groups, for which the electron temperature
could be determined. The ${\rm O}^{++}/{\rm H}^{+}$ and ${\rm S}^{+}/{\rm H}^{+}$~abundances are the average of the two values obtained from the two
lines of the doublet separately ($\lambda\lambda5007,4959$, and $\lambda\lambda6716,6731$,
respectively).}\label{tabcap:Physical-parameters-and}
