\caption{Data for the \lz\ relation of Sculptor and M~81 dIrrs, taken both
from the literature and from the present work. The abundances, computed
with the method identified in the third column, have been extracted
from the publication identified by its acronym in the fourth column
(see the bibliography); S08 is this paper. The abundance methods are
D~= direct, M~= McGaugh, P~= Pilyugin, and I~= indirect. Notes on abundances
are: (a)~average of 3~regions; (b)~average of two methods; (c)~central
region; (d)~external region. Distances have been computed with the
method identified in the sixth column, and have been extracted from
the publication identified by its acronym in the seventh column (see
the bibliography). The distance methods are J98, assuming an error
of $20\%$ and RGBT~-- red giant branch tip. Total apparent $H$-band
magnitudes are from this work, and the $H$-band extinctions are from
Schlegel et~al. (\cite{schlegel_etal98}).}\label{tab:Data-for-the-LZ}
