WebHere, we present a method for deprojecting barred galaxies and we validate the method by testing against mock images created from an N-body silation with a peanut-shaped bar. We decompose a galaxy image into a bulge (including a bar) and a disc. By subtracting the disc from the original image a barred bulge remains. Webof barred galaxies and Merritt & Fridman (1996) and Merritt (1996a) used it to build a number of triaxial models with cusps. Zhao (1996b) modeled the Galactic bar using similar techniques.
