Comparing the \lya/H$\beta$ ratio with the theoretical
expectation from case B recombination of $23.3$ \citep{Hummer1987} one
can estimate an escape fraction of $20$\% for \lya radiation.
Figure \ref{fig:results} shows \tol's \lya\ profile reported by
\cite{mashesse03}. This measurement as mede with the Space Telescope
Imaging Spectrograph on board the Hubble Space Telescope, these
observations have a spectral resolution of $\sim 37$\kms\ at the
\lya\ wavelength.
The \lya flux values correspond to a luminosity of
$L_{Ly\alpha}=2.2\times 10^{42}$ erg s$^{-1}$, which in turn

Reply.

My main concern with the final result (and the corresponding
interpretation) of this paper is that the dynamical masses may have
been overestimated somehow. Recently, Oyarzun et al. (2016) have
pointed out to the existence of a correlation between Ly-alpha
equivalent widths and stellar masses in the sense that lower stellar
mass galaxies have higher Ly-alpha equivalent widths. Is it possible
that this effect, if not corrected for, may be causing to measure
higher velocity values from the Ly-alpha profile that also result into
higher dynamical masses?

Reply. We have looked carefully into published observational data for
compact dwarf galaxies (UCD's) and dwarf ellipticals (DE's).

Reply. The high velocity come from the high line-width. Not from its
Equivalent Width (i.e. intensity to continuum ratio). The effects of
Oyarzun et al. 2016 should not change our conclusions.
