1. 2008MNRAS.388..500E
Re:UGC 11332
UGC 11332 (NGC 6654A). There is a good agreement between our H{alpha} map and
that of James et al. (2004). However, our image is affected by very bad seeing
conditions (see Table C2) resulting in a diffuse emission around the galaxy that
is most probably an artefact. No H I velocity map is available in the
literature. The width of the H I profile at 20 per cent (331 km s^-1^ from
Springob et al. 2005, 315 km s^-1^ from Bottinelli et al. 1990) is significantly
larger than our H{alpha} velocity field amplitude (about 200 km s^-1^),
suggesting that our H{alpha} velocity field does not reach the maximum rotation
velocity althougH It extends up to the optical radius.
