tileA 1.49 deg radius circle on the sky determined by tiling and which contains the locations of up to 592 tilable targets and other science targets. For each tile one or more plates will be created. If less than the maximum of 592 tilable targets can be assigned to that tile, the spare fibers are assigned to other spectroscopic targets. The 48 remaining fibers will be assigned to calibration targets.
