NGC 7187 (double bar + inner disk): Buta (1990b) and Wozniak et al.
(1995). Outer-disk inclination and PA are from Buta; bar
measurements are based on those of Buta and Wozniak et al. (1995).
Adopted outer-bar length is that of the inner ring surrounding it.
Wozniak et al. (1995) identified this a triple-barred galaxy;
however, the middle "bar" is low enough in ellipticity and close
enough in alignment to the outer disk to qualify as an inner disk,
making this galaxy similar to NGC 3368, NGC 3945, and NGC 4785.
NGC 7187 (Fig. 7, top).--A very weak bar crosses the bright inner ring in the
red continuum image. H II regions line about two-thirds of the ring. These are
brightest near the bar ends. There is only one clear H II region in the very
faint outer ring, and there is significant nuclear emission. The galaxy is also
discussed by Buta (1990a) and Wozniak et al. (1995).
