Notes. Properties of the different components identified in Fig. 1. (1) Name of the component. (2) and (3) Distance in RA and Dec from the central (main) source at co-ordinates RA 03h32m23.3497s, Dec –27° 51
57.13″. (4) Semi-axes of the ellipse used as extraction aperture. (5) Angle of the major axis of the ellipse used as extraction aperture measured east of north (anticlockwise). (6) SFR derived from the dust-corrected Hα luminosity using the relation from Kennicutt & Evans (2012), assuming a Chabrier (2003) IMF. (7) Extinction derived from the Balmer decrement, assuming a Cardelli et al. (1989) attenuation law. (8) Metallicity calculated from the R3, O3O2 and R23 calibrations from Curti et al. (2020b). (9) Ionisation parameter inferred using the S2S3 calibration from Díaz et al. (2000). (10) Electron density estimated from the simultaneous fit of the [S II] and [O II] line ratio, using the formulas from Sanders et al. (2016), assuming the typical electron temperature of HII regions Te = 104 K. (11) Velocity with respect to the redshift of the narrow component of the main target (z = 3.4705 ± 0.0001). (12) Velocity dispersion. ( * )For the main target, we show the properties inferred from the fit with one component, and the properties derived separately from the narrow and broad component of the two components fit.
