Notes: a Relative distance between the radio continuum emission peak and the maser spot. b In parenthesis sources candidates to PN or candidate to WF. WF: water fountain characteristics. c This source is a previously reported OHPN candidate (Cala et al. 2022). d The flux density at 3 GHz was reported in VLASS (Gordon et al. 2021), and the 1665 MHz was reported in THOR (Beuther et al. 2019).
