Notes. ⁽¹⁾ Quantities are averaged over the x, y, and z projections. ⁽²⁾Distance to the region. ⁽³⁾Angular resolution. ⁽⁴⁾Linear scale corresponding to the angular resolution. ⁽⁵⁾Total number of sources in the extraction catalogues. ⁽⁶⁾Number of selected bound sources. ⁽⁷⁾Median mass of bound sources. ⁽⁸⁾Mean mass of bound sources. ⁽⁹⁾Equivalent half-maximum diameter (A + B)∕2. ⁽¹⁰⁾The mass drops to ≃ 1585 M_⊙, if the most massive source is ignored.
