AN X-RAY-ANALYSIS OF THE CD CLUSTER ABELL-2199

We describe the ROSAT analysis of the cD cluster Abell 2199. The spati al distribution is found to be slightly elongated, with an axis ratio of approximate to 0.8 and position angle of approximate to 45 degrees anticlockwise from due North about the cluster centre. The surface bri ghtness profile reveals a significant cooling flow of approximate to 2 50 M. yr(-1), although a lower mass deposition rate is deduced from th e spectral data. The total gas and gravitational masses within a radiu s of 1.8 Mpc are found to be approximate to 1 x 10(14) Mg and approxim ate to 5 x 10(14) M. respectively. The implications of these findings are discussed.
