Descripción
We present the first results of an observational project aimed at
producing a database of nearby face-on spiral galaxies in the optical.
The project is being run at the IAC-80 telescope in Tenerife. This first
sample is made of from R and I images of NGC 428, 864, 2146, 2273, 2541,
2967, 4618, 4654, 6217, and 6643. Overall geometrical parameters are
obtained via ellipse fitting to the observed surface photometry. Then,
structural decomposition into the main morphological components are
performed via simultaneous fitting of their analytical brightness
profiles to the measured global radial profile. The characteristic
structural and photometric parameters of those components are so
obtained. It is noticeable that the sample is fully composed by barred
galaxies, even when some of them are not classified as such in the RC3
catalog. The bars have first been identified in the radial profiles
obtained in the ellipse fitting, and subsequently their brightness
distribution taken from the global radial intensity profile.
