contains highly inclined galaxies in which warps should be easy to detect. This could introduce a bias against early types or galaxies with prominent bulges that should be taken into account in the discussion of the warp phenomena. Using this approach, we try to avoid the common confusion between spiral arms, corrugations, and warps.
