Projected correlation function for the CLASXS and CDF‐N fields and the combined sample. (a)–(c) Best‐fit parameters, as well as the χ² contours for the CLASXS+CDF‐N sample, the CLASXS sample, and the CDF‐N sample, respectively. Contour levels are for 1, 2, and 3 σ confidence levels. (d) Projected correlation function for CLASXS (open circles) and CDF‐N (black dots) fields. Lines are the best fit shown in (a)–(c). Solid line, CLASXS+CDF‐N; dotted line, CLASXS; dashed line, CDF‐N.
