We present an optically selected galaxy cluster catalog from ~ 2,700 squaredegrees of the Digitized Second Palomar Observatory Sky Survey (DPOSS),spanning the redshift range 0.1 < z < 0.5, providing an intermediate redshiftsupplement to the previous DPOSS cluster survey. This new catalog contains9,956 cluster candidates and is the largest resource of rich clusters in thisredshift range to date. The candidates are detected using the best DPOSS platesbased on seeing and limiting magnitude. The search is further restricted tohigh galactic latitude (|b| > 50), where stellar contamination is modest andnearly uniform. We also present a performance comparison of two differentdetection methods applied to this data, the Adaptive Kernel and VoronoiTessellation techniques. In the regime where both catalogs are expected to becomplete, we find excellent agreement, as well as with the most recent surveysin the literature. Extensive simulations are performed and applied to the twodifferent methods, indicating a contamination rate of ~ 5%. These simulationsare also used to optimize the algorithms and evaluate the selection functionfor the final cluster catalog. Redshift and richness estimates are alsoprovided, making possible the selection of subsamples for future studies.
