Query: Optical Photometric and Spectroscopic study of the Seyfert Galaxy SBS
  0748+499   We present the first optical photometric study of the active galaxy SBS
0748+499. First, we present B, V, R and I photometric data: total magnitudes
and B-V, B-R, B-I colors; surface brightness, color and geometric profiles,
with emphasis on the morphology and its relation to the global photometric
properties of this galaxy. Then, from our surface photometry study we derive
the bulge-to-disk luminosity ratio B/D in the four bands. We find that the host
galaxy shows a bar (a ~ 8 kpc) and a low-brightness spiral structure. The
morphological classification for the host galaxy of this AGN is SBab.
Additionally, we present new optical spectrophotometric observations that
clearly show that the object can be classified as Sy 1.9 galaxy. Finally, we
estimate the black hole mass (M_BH) associated with the nucleus of SBS 0748+499
using the absolute R-band bulge magnitude - M_BH relation, and the FWHM
[OIII]_5007 - sigma_{star} relation. We find that M_BH = 2.6 x 10^7 M(sun) and
M_BH = 8.8 x 10^7 M(sun), respectively.
