Descripción
A catalog of optical warps of galaxies is presented. This can be
considered complementary to that reported by Sánchez-Saavedra et
al. (cite{sanchez-saavedra}), with 42 galaxies in the northern
hemisphere, and to that by Reshetnikov & Combes
(cite{reshetnikov99}), with 60 optical warps. The limits of the present
catalog are: logr 25 > 0.60, B_t< 14.5, delta (2000) <
0deg, -2.5 < t < 7. 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.
