“Box/Peanut”- Shaped Galactic Bulges
By a visual inspection of photographic plate material for all 504 of the largest, normal spiral and lenticular galaxies contained within the Second Reference Catalogue (de Vaucouleurs et al. 1976; RC2) and supplementary lists, we have constructed a subset of those 117 systems which are most edge- on to the line-of-sight. This has been used as a basic database for our investigation of the nature of the galaxian non-thin disc population in general, but it has also proved an ideal means by which to study general characteristics of those galaxies which display “box” or “peanut”-shaped central isophotes.
