The information path to prepare, perform and reduce a radioastronomical observation, using the Arcos correlator , is schematized in the figure: . The programs reside part on the computer network of the Arcetri Observatory, and part at the Medicina Radio Telescope . All programs running at Arcetri are written for a Sun workstation, and are public domain software, available upon request. Programs running at the telescope are written for a PC with DOS/Windows (or Linux).

. Comment on J1842+7946 . Comparing the brightnesses of the two main features seen in our 5 GHz image with higher frequency VLBI images available in the literature (at 8.4 GHz from the USNO database and at 15 GHz by Kellermann et al. (1998)), one can conclude that the NW component has a steeper spectrum since the SE one becomes relatively stronger as the observing frequency increases. VLBApls home page .

... For queued observations, the nightly scheduling will be performed by sta# astronomers using an Operational Toolkit. ... The toolkit will make all observation preparation data available to the oper­ ator, and will allow the definition of queues and timelines of Observation Blocks (OBs). ... The operations team then uses the Operational Toolkit to browse the repos­ itory and build queues, based on object visibility, expected observing conditions, and user­defined scheduling constraints. ...
