Different slices through the phase space of Agg17 (COIN-Gaia 40, Gulliver 53, Kronberger 1, NGC 1893, Stock 8), together with the complete colour-magnitude diagrams (based on Gaia and 2MASS photometry). Top-left: distribution of parallaxes of all individual stars in Agg17. Duplicates are excluded. Top-right: histogram of parallaxes, excluding the duplicate cluster members. The best fit was achieved with the following double-Gaussian function parameters: ϖ₁ = 0.331 ± 0.006 mas, σ₁ = 0.022 ± 0.007 mas, ϖ₂ = 0.440 ± 0.005 mas, σ₂ = 0.064 ± 0.005 mas. Middle-left: coordinates of the stars in Agg17. Size of the points indicates values of the observed magnitude G. Middle-right: proper motion diagram of Agg17. Bottom-left: colour-magnitude diagram of Agg17, based on the observed values of B_P − R_P and G). Bottom-right: colour-magnitude diagram of Agg17 based on 2MASS photometry. The stars were located using the coordinates in Gaia database.
