Non-classified objects

39 non emission-line objects are hard to classify. Their continuum have too low signal-to-noise ratio to detect trustworthy absorption features, or small EW emission lines. 18 of them are certainly non-stellar on DSS images. For half of these galaxies we have spectra only in the range $\approx$ 4000 to $\approx$ 5400 Å, and they could have emission in H$\alpha$. For the other half we have spectra in the range $\approx$ 4000 to $\approx$ 7000 Å, and we can exclude the presence of strong H$\alpha$. The remaining 21 objects are indistinguishable from stellar ones, and we suggest that most of them are galactic stars.
