DIABOLO which currently employs two linear arrays of 3 pixels, centred
respectively at 1.2 mm and 2.1 mm, respectively, is designed
for detection of weak and somewhat extended sources. The instrument which
was used successfully at the 30m telescope last winter, is
described by X. Désert elsewhere in this newsletter. The level of integration
of the instrument into the 30m telescope's standard control and acquisition
system is minimal, however, complicating the use of this instrument.
Obervers interested in using DIABOLO should contact
X. Désert at the Observatoire de Grenoble for arranging some form of
collaboration.
