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.
