Scattering Effect on Photometric Plane in measuring galaxies distance

Abstract

In this study, a sample of elliptical and lenticular of boxy and disky types has been choose, 15 galaxies belong to Virgo cluster, The photometric plane (PHP) for these galaxies has been calculated. The photometric plane is represented by the following equation with a vertical scatter of 1.47 in re, This scatter translates to a 47 per cent error in distance per galaxy. This study also show the disc galaxies increase the scatter in the calculation of the plane. The scatter decrease 1.29 in re, in case using only the boxy-shape galaxies. This scatter translates to a 29 per cent error in distance per galaxy.
