Notes. (a)The Roman squid flux density and the spectral index were calculated on the complete source and not as the sum of the four subcomponents A, B, C, and D.(b)Sources A, B, C, G78.4+2.6, C2, and YSO were catalogued in Benaglia et al. (2020) as BIC610-0666, BIC610-0665, BIC610-0672, BIC610-0676, BIC610-0737, and BIC610-0808, respectively. Sources C1-W and C1-E were catalogued as BIC610-0895 and BIC610-0916, and sources C1-MN and C1-MS were catalogued as a unique source, BIC610-0898. (c)Ultra compact H II region called VLA 1 by Neria et al. (2010). (d)Hard X-ray source (Uchiyama et al. 2002; Leahy et al. 2013).
