An X-ray optical study of 26 Abell clusters.

We present results of an X-ray optical study of 26 Abell clusters. We have used Einstein IPC images of clusters, taken from our complete sample of 107 clusters with richness 1 or greater and with redshift less than or equal to 0.1, to measure X-ray position angles. We find our X-ray position angles are in good agreement with those taken from a concurrent study by McMillan et al. We find a very good agreement between the centroid of the X-ray emission and the position of the first ranked galaxy. We find a good correlation between the cluster position angle measured using X-rays, the cluster orientation derived from the galaxy distribution and orientation of the first ranked galaxy.
