Scientific paper
From DDO photometry an indicator of barium stars has been elaborated.
This indicator is closely related to the barium line intensities derived
by means of narrow-band photometry and spectroscopic observations. A
better discrimination appears when this indicator is used instead of the
qualitative index of Warner (1965).
