Spatial distribution of GC velocities (top) and metallicities (bottom). The large panels on the left show the full distribution of velocities and metallicities, respectively. Circles refer to this work; triangles refer to GCs listed in the Dowell et al. (2014) and Alves-Brito et al. (2011). Black crosses show dwarf galaxy candidates near M 104 from Crosby et al. (2024). The smaller panels on the right side show the velocities and metallicities in different bins, as indicated in the panel titles. Fig. B.1 shows a zoom-in of the central 5′ × 5′.
