We present in catalog form the optical identifications for objects from thefirst phase of the Wide Angle ROSAT Pointed Survey (WARPS). WARPS is aserendipitous survey of relatively deep, pointed ROSAT observations forclusters of galaxies. The X-ray source detection algorithm used by WARPS isVoronoi Tessellation and Percolation (VTP), a technique which is equallysensitive to point sources and extended sources of low surface brightness.WARPS-I is based on the central regions of 86 ROSAT PSPC fields, covering anarea of 16.2 square degrees. We describe here the X-ray source screening andoptical identification process for WARPS-I, which yielded 34 clusters at0.06
