Scientific paper

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 ~ 250 ; Msun; yr(-1) , 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 ~ 1x 10(14) ; Msun and ~ 5 x 10(14) ; Msun respectively. The implications of these findings are discussed.
