Different slices through the phase space of Agg07 (Alessi 5, BH 99), together with the complete colour-magnitude diagrams (based on Gaia and 2MASS photometry). Top: histogram of parallaxes, excluding the duplicate cluster members. The best fit was achieved with the following double-Gaussian function parameters: ϖ₁ = 2.225 ± 0.007 mas, σ₁ = 0.087 ± 0.007 mas, ϖ₂ = 2.501 ± 0.006 mas, σ₂ = 0.061 ± 0.006 mas. Middle-left: coordinates of the stars in Agg07. Size of the points indicates values of the observed magnitude G. Middle-right: proper motion diagram of Agg07. Bottom-left: colour-magnitude diagram based on the observed values of B_P − R_P and G). Bottom-right: colour-magnitude diagram based on 2MASS photometry. The stars were located using the coordinates in Gaia database. The two clusters remain distinguishable in this photometric system.
