Abstract: | The variation in the direction of the major axis in three ellipticals, five lenticulars and three spirals has been studied using B or V isophotic maps. It is noticed that there is a turn point in most of the curves especially for spirals and lenticulars. This turn point can be used to define the galaxy nucleus region. There seems to be a correlation between the rotation curve and the position angle curve especially for NGC 2784 and NGC 3640 |
