Re:IC 1438
IC 1438 (Fig. 5r).-This barred galaxy hosts a complete ring with 11 H II regions
detected. There exists an increasing age gradient from PA = 32^deg^ to 211^deg^
in a counterclockwise direction. This direction is consistent with the ring
rotational flow. The youngest H II region is within 2^deg^ of its respective bar
contact point (PA = 304^deg^ ).

Re:IC 1438
IC 1438: the HII regions are placed mainly in the arms and
the ring of this nearly face-on galaxy. The two methods are
in good agreement. But as there is no background disk of HII
regions, the first method may be biased by the presence of
the spiral structure. We thus keep the PA from the second
method, which coincides with that found by Crocker et al.
(1996). For the IA we take the average of our two methods.

Re:IC 1438
IC 1438 (Fig. 9, middle).--The H II regions in the inner ring are very clumped
at the bar ends; away from the bar ends they are much fainter and fewer in
number. The outer arms are very bright in H{alpha} in the quadrants trailing
the bar only. They follow the R'_2_ part of the outer structure most closely,
as in NGC 1326 and 6782. The center has a clear nuclear ring of H II regions
(see close-up view in Fig. 12). This ring is completely filled with diffuse
emission. There is a bright nuclear source also. A few faint H II regions lie
on both leading edges of the bar. The outer H{alpha} arms begin nearly along
the bar axis. An asteroid passed through the field at the time of the
observation and left the streaks to the northwest of the galaxy center.
