The developpement of the Bordeaux VLBI Image Database (BVID) was possible thanks to the support of:

Observatoire des sciences de l'univers Pythéas (OSU Pythéas)
Datacenter Sud - Aix Marseille Université
52 Avenue Escadrille Normandie Niemen
13013 Marseille
France

Sean Raymond, Laboratoire d’Astrophysique de Bordeaux (LAB)

Arnaud COLLIOUD-MARICHALLOT, Laboratoire d’Astrophysique de Bordeaux (LAB)

Current lead developer : Julien Penguen (UAR POREA)
Associated developer : Arnaud Collioud (LAB)
Past lead developers : Benjamin Pavone, Mathieu Gauthier-Lafaye, Fabrice Mendes (UAR POREA) Arnaud Collioud (LAB) The BVID has been developed using HTML, CSS, javascript (Bootstrap framework) and PHP (Symfony framework).
The template used is AdminLTE. This template provides an HTML responsive web design to make the BVID display well on all devices (desktops, tablets, and phones).

Plots, maps and graphs are produced with Plotly.js and D3.js libraries.

We recommand the use of Mozilla Firefox since the BVID interface has been extensively tested on this browser. Login page: An artist’s rendering of the most distant quasar, M. Kornmesser (ESO)
