Number counts of quasars in the SDSS i-band. Solid circles and triangles show the SDSS-DR3 number counts for 0.3 < z < 2.2 and 3 < z < 5, respectively. Open circles and triangles give the values from this catalog (restricted to good ⩾ 0). The 2QZ/6QZ number counts are given by open squares. The photometric samples are highly contaminated at bright magnitudes. No corrections for efficiency or completeness have been applied; thus, this comparison is not ideal. Also note that the log–log nature of this plot means that even large discrepancies can appear quite small, but the general agreement is nevertheless reassuring.
