It is used to observe the
hydrogen line from our galaxy and
maser signals from
s and late evolution
AGB or
OH/IR stars. The frequencies used for the
hydrogen line is 1.42 GHz and
maser signals are measured on 1.612, and 12 GHz
The data results obtained with the telescope were presented on EUCARA 2016 Dwingeloo Netherlands
