ACIS-S+I image of the clusters field, smoothed with a 3″ Gaussian kernel. The bright cluster WARPJ1415 at z = 1 is visible in the upper right, whereas CXO1415 lies at ~2′ in the south-west direction. The solid circles have a radius of 35″ (corresponding to 300 kpc at z = 1.46), whereas the dashed circle with r = 24″ refers to the aperture of maximum S/N used for the spectral analysis. The image has a size of 4′ × 4′.
