“…If we consider the upper age limit of 5 Myr for NGC 602, this escape velocity would account for a distance of about 13 pc of a star from the cluster. Interestingly, this is almost identical to the projected radial distance, ∼ 12 pc, of the most remote massive star, the O6 dwarf star #8 in Hutchings et al (1991) catalog. It is worth noting that 50% of the hot massive stars in this catalog are located outside the boundaries of NGC 602, as they are defined by the 2σ isopleth in the density map of Fig.…”

“…The intensity of the He II λ4026 absorption is also relatively strong for an O3 type dwarf, but may be explained by a contribution from He I. We note that Hutchings et al (1991) classified their low-dispersion optical spectrum of Sk 183 as O6, but the lack of strong He I λ4471 absorption in their data argues for an earlier type.…”

“…Source 4 Source 4 is 1. ′′ 04 (∼ 0.3 pc) from star HTCP 2 (Hutchings et al 1991), which they classified as O9. HTCP 2 was later resolved into a close pair of stars by the HST imaging (see Fig.…”
