Summary of observations, with columns as follows: (1) Source designations identify them in the catalogue of Peretto & Fuller (2009); (2)–(3) Coordinates of the NOEMA pointings; (4) Systemic velocities from Peretto et al. (2023); (5)–(6) Heliocentric distance and uncertainty; (7)–(8) Major and minor axes of the synthesized beam and rms sensitivity of the 2.8-mm continuum; (9)–(10) Major and minor axes and rms sensitivity of the N2H+ (1–0) observations; (11) Total clump mass contained within a 1-pc-diameter aperture; (12) Bolometric luminosity of compact sources within a 1-pc aperture; (13) Infrared-bright fraction within the 1-pc aperture; and (14) Maximum filament convergence parameter within the 1-pc aperture. The top seven rows are our new NOEMA observations, while the bottom six rows correspond to the adapted ALMA observations of Anderson et al. (2021). An electronic version of this table is provided as supplementary material.
