Description:
A sample of 54 nearby spiral galaxies was observed in the K' band with
3.5m NTT telescope, La Silla, ESO, to study the morphology and other
properties of spiral perturbations in their disks. A subsample of the
galaxies classified as ordinary, non-barred spirals was used to
estimate frequency of weak bars detectable in the K' band.
The tables provide general structural properties of the galaxies
including estimated of the bulge/disk decomposition and spiral
perturbations in the disks.
