F. Hammer, O. le Fevre, D. Proust, Observatoire de Paris, Meudon,
and Canada-France-Hawaii Telescope Corporation, telex: "New deep,
high-spatial-resolution spectroscopy of 3CR 368, obtained with the
European Southern Observatory's 3.5-m New Technology Telescope,
confirms the unrelated and foreground nature of the brightest optical
component. However, higher signal-to-noise and improved calibration
on the detected continuum reveals that it is probably a giant galactic
star rather than a foreground galaxy. Important consequences on
the properties of 3CR 368 will be derived from these data."
