(a) Projected, emission‐averaged, model temperature distribution superimposed on the 90% confidence limits from ASCA (error bars) for A1060. The best‐fit mass model, a_dark = 325 kpc (solid line); the most compact acceptable mass model, a_dark = 150 kpc (dotted line); and the most diffuse acceptable mass model—a_dark = 900 kpc (dashed line) are indicated. (b) Same as (a) but for AWM 7 with a_dark = 300, 100, and 650 kpc for the best‐fit, most compact, and most diffuse dark matter models, respectively.
