... kelvins

The angular offset from the test position was defined as either the offset of the object's peak temperature position or the offset of the object's centroid position, whichever was closest.

.... 

In the case that, at most, only one object is present along any line of sight, $N_{\rm E}({\leq}\delta r,~{\geq}T_{\rm p})$ would always be $\leq$1 and would be the probability of chance association within $\delta r$, above $T_{\rm p}$. However, this is not the case; $N_{\rm E}({\leq}\delta r,~{\geq}T_{\rm p})$ is thus an expectation value, and could exceed unity.

... criteria

If they lie within the WB89 region, they were not included in the WB89 sample because they failed the $\log(100/60)$ colour constraint not shown in the figures.

... Galaxy

Here we adopt the canonical definition of "far'' as meaning objects with a Galactocentric distance of $R_{\rm G} >16$ kpc.
