Upper panel: FMOS pawprint overlaid on the HST/ACS mosaic of the COSMOS field (Koekemoer et al. 2007; Massey et al. 2010). Large circles show the FoV of each FMOS pointing. The central area of 0.81 ﹩{\deg }^{2}﹩ covered by four FoVs (HR1–HR4) are highlighted by red. Lower panel: on-sky distribution of all galaxies in the FMOS-COSMOS catalog (gray circles). Red circles indicate those with any spectroscopic redshift measurement (1931 objects with ﹩z\mathrm{Flag}\geqslant 1;﹩ see Section 5). The pawprints visited in the J-long mode are highlighted by thick blue circles.
