Description:
We present K'-band surface photometry of a sample of 31 inclined
Sa-Scd galaxies, together with additional J- and H-band data for four
of them. In this first paper of a series, profiles are presented,
together with global and isophotal parameters. Our profiles are
compared to similar B, R and I data collected from other sources.
Three galaxies exhibit previously unknown small bars in their center
while in five others, such bars may also be present. Four objects
present a narrow elongated feature in their center aligned with their
major axis, which could be an inward extension of the disk. A few
galaxies display very thin spiral arms. Color-color diagrams indicate
that the extinction inside the four galaxies for which we have JHK'
images is limited to A_V<2.
