Abstract

We present optical and near-infrared (NIR) surface brightness and colour profiles,in bands ranging from U to K, for the disk and bulge components of 30 S0-Sbc galaxies. We give details on the observations and on the determination of colour parameters. Results are given in graphical and tabular form. Calibrated monochromatic and real-color images are presented, as well as colour index maps. These data is particularly suited to the study of the population characteristics of galaxy bulges; in related papers, we have used them to quantify bulge colour gradients, and age differentials between bulge and inner disk.
