A catalog of optical warps of galaxies is
presented. This can be considered complementary to that reported by
Sánchez-Saavedra et al. ([CITE]), with 42 galaxies
in the northern hemisphere, and to that by Reshetnikov & Combes
([CITE]), with 60 optical warps.
The limits of the present catalog are:
,
,
. Therefore, lenticular
galaxies have also been considered. This catalog lists 150 warped
galaxies out of a sample of 276 edge-on galaxies and covers the whole
southern hemisphere, except the Avoidance Zone.
It is therefore very suitable for statistical
studies of warps. It also provides a source guide for detailed
particular observations. We confirm the large frequency of warped
spirals: nearly all galaxies are warped. The frequency and warp angle
do not present important differences for the different types of
spirals. However, no lenticular warped galaxy has been found
within the specified limits. This finding constitutes an important
restriction for theoretical models.
