Re:UGC 07971
UGC 7971 (NGC 4707)
The H{alpha} emission of this magellanic spiral is concentrated in
a few bright HII regions at the periphery of the main body. It is thus
impossible to draw a velocity field and we just give the approximate
velocity values for the 5 brighter HII regions, from which one can
hardly guess the position of the major axis. The derived rotation
curve is not very significant because of the paucity of the H{alpha}
emission. The WHISP HI data show a large HI hole in the center of the
galaxy, the HI gas appearing as a ring surrounding the main optical
body. The WHISP HI velocity field suggests a solid body rotation with
a small amplitude, as confirmed by the HI rotation curve derived by
Swaters (1999). No clear comparison with our H{alpha} curve is possible
because of the high dispersion of our points. Indeed, the low values
of the rotation velocities we find in the outer parts, on the receding
side, are produced by two HII regions only, the motions of which may
not be representative at all of the average motion in the disk.
