Notes. The starting observation time of 3 Puppis is given in the UTC convention and with the units of hours:minutes:seconds. Bmax and Bmin are respectively the longest and the shortest projected baseline separation lengths used during the observations. The so called ‘large’ configuration in this table refers to the old VLTI baseline configuration (config.), that is to say before the ESO call for proposal P112. The ‘extended’ baseline configuration has been offered to the community since 2023.
