Re:[Sdd95] 117a
P117a (S(s)a): this object is classified as S0 in RC3. However, we found
evidence of spiral arms on it. The central region is slightly bluer, contrary to
the indication of the ESO-LV catalog. Nevertheless, our color map is in
agreement with our spectroscopic data: this spiral exhibits strong central
emissions and peculiar N spectra (Couto da Silva & de Souza 2006). There is a
small variation in the PA distribution, {DELTA}PA_{bd} ~ 4^deg^, probably
related to the fluctuations in spiral arms' orientation. The mean values for the
ellipticity distribution are {epsilon}_b_ ~ 0.38 and {epsilon}_d_ ~ 0.26. The
{epsilon}(r) distribution is slightly rounder outward.
