We describe the ROSAT analysis of the cD cluster Abell 2199. The spatial distribution is found to be slightly elongated, with an axis ratio of ≃0.8 and position angle of ≃45 degrees anticlockwise from due North about the cluster centre. The surface brightness profile reveals a significant cooling flow of ≃250M_☉/yr, although a lower mass deposition rate is deduced from the spectral data. The total gas and gravitational masses within a radius of 1.8 Mpc are found to be ≃1x10¹⁴M_☉ and ≃5x10¹⁴M_☉ respectively. The implications of these findings are discussed.
