Image Details
Caption: Fig. 1.
False‐color X‐ray image (﹩25^{\prime }\times 25^{\prime }﹩) of the LALA Boötes field, composed from a 172 ks Chandra exposure. North is to the top, and east is to the left. The image was obtained by combining three energy bands: 0.3–1.0, 1.0–2.0, and 2.0–7.0 keV (red, green, and blue, respectively). The color intensity is derived directly from the counts and has not been corrected for vignetting.
