ABSTRACT
We have obtained deep J and Ks images of a sample of nine barred galaxies in order to collect
a reliable and homogeneous set of images to which N-body simulations of barred galaxies will
be compared. The observations were performed using the new near-infrared camera available
at the 2.1-m telescope of the Observatorio Astrof´isico Guillermo Haro (OAGH) in Cananea,
Sonora, Mexico. We present the results of surface photometry techniques applied to the ob-
served images, as well as to the deprojected images. These results include radial profiles of
