Description:
Observations with the HEAO 1 scanning modulation collimator (MC) have yielded improved locations for the centroids of X-ray sources in clusters of galaxies dominated by a giant central galaxy. For A85, A478, A1795, A2029, A2199, A2319 A, and SC 0316-444, these positions are consistent with those of the clusters' dominant cD galaxies. By comparing the HEAO 1 MC flux with that obtained with the HEAO 1 A-2 experiment, estimates of the X-ray sizes for these clusters have been obtained. The correlation of these sizes with other cluster properties is discussed.
