Scientific paper

Principal component analyses have been conducted on a large sample of edge-on galaxies displaying 'box' or 'peanut' shaped bulge distortions in order to identify the characteristic photometric properties of the morphology. The identified parameter space is strictly two-dimensional, indicating that no single parameter exists by which box/peanut morphology could be fully characterized. The most significant parameters are measures of bulge dimension, and the bulge-to-total luminosity ratio. It is shown that weak boxes and extreme peanuts are merely extrema in a homogeneous family of isophotal distortions. The results also suggest that the disk component is not an important constraint on the formation and/or subsequent evolution of box/peanut bulge distortions.
