Notes. One object (B331) was detected earlier in VLA observations. (a) Dust mass estimate based on Eq. (2) assuming that the flux in this band is purely from dust emission. (b)Flux in the VLA X-band (10 GHz) according to Yanza et al. (2022). For nondetections an upper limit is given. (c)Spectral index between ALMA Bands 6 and 7, given by Eq. (1). (d) Rodríguez et al. (2012) report VLA fluxes of 0.46 ± 0.10 and 0.66 ± 0.07 mJy at 4.96 GHz and 8.46 GHz, respectively. (e)The spectral index between ALMA Band 6 and VLA 10 GHz is α = 0.53 ± 0.06. Rodríguez et al. (2012) report an index between VLA points 4.96 GHz and 8.46 GHz of α = 0.7 ± 0.5. (f)Only detected in Band 7, not subjected to further analysis. (g)This object was imaged with a uv-taper of 0.08″ to increase S/N.
