caption: Radio core luminosity (evaluated at or near 5 GHz) versus redshift for all objects from the LRL sample with 0.65≤z<;1.20 plus additional UKIRT targets. UKIRT targets are indicated by large symbols: large circles denoting LRL objects, and large squares denoting objects which are only in 3CR. The smaller symbols have meanings as follows: filled squares represent quasars (class 'Q'); filled triangles, radio galaxies with broad lines prominent in direct-light spectra ('B'); filled stars, radio galaxies with broad lines seen only because of a large scattered (polarized) component ('S'); and open squares, narrow-line radio galaxies ('G'). The numbers in each category in each of three marked redshift bins are summarized at the top of the plot, with the first number relating to the total number in LRL, the second to the number of LRL objects observed with the UKIRT, and the third number to the 3CR (only) UKIRT targets. A few objects of special interest are labelled.
