Layout of the focal plane for the FPS used by SDSS-V. The layout shown is as built for APO; the LCO layout is nearly identical. The X- and Y-axes are position in the focal plane, with the boresight at X= Y = 0 mm. We show each positioner as an annulus describing its patrol area. The pink annuli are the 298 positioners that carry both BOSS and APOGEE fibers. The gray annuli are the 202 positioners that carry a BOSS fiber but not an APOGEE fiber. The focal plane is divided into eight zones, as labeled, for the purposes of distributing APOGEE standard stars. The fiber reach extends to around 315.5 mm in radius at the vertices of the hexagon, or about 1 ﹩\mathop{.}\limits^{\unicode{x000b0}}﹩ 422 at APO and 0﹩\mathop{.}\limits^{\unicode{x000b0}}﹩ 953 at LCO, accounting for the radial distortions at the edge of the field. This reach yields a solid angle within the hexagon of 5.255 deg² at APO and 2.360 deg² at LCO.
