P. Heraudeau et al., NEAR-INFRARED SURFACE PHOTOMETRY OF SPIRAL GALAXIES .1. THE DATA, Astronomy & Astrophysics. Supplement series, 117(3), 1996, pp. 417-444
We present K'-band surface photometry of a sample of 31 inclined Sa-Sc
d galaxies, together with additional J- and H-band data for four of th
em. In this first paper of a series, profiles are presented, together
with global and isophotal parameters. Our profiles are compared to sim
ilar B, R and I data collected from other sources. Three galaxies exhi
bit previously unknown small bars in their center, while in five other
s, such bars may also be present. Four objects present a narrow elonga
ted 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 Av < 2.
