2. The ESO VLT CCD Detectors Software
... Charge Coupled Devices (CCD) are currently by far the most widely used type of detector in astronomy. ... After a brief introduction to the VLT Control System, the VLT CCD Detectors Control Software is presented. The VLT Control System is a distributed system consisting of a set of UNIX Workstations, dedicated to high level operations, such as coordination of sub-system activities and interface to the users, and VME-based Local Control Units (LCU), dedicated to the control of sub-systems hardware. ...

3. Electric Currents from Space
... This limited extent suggests that the currents which disturb the field flow somewhere nearby, probably near the auroral arcs. ... Any electric current, however, must flow in a closed circuit, and since it seemed to be caused (like that of the aurora) by processes taking place in distant space, Birkeland proposed that it came down from space at one end of the arc and returned to space at the other end. ... The electric energy needed to drive the current is taken from the motion, which is slowed down....

... ALMA . ... OOF software . ... Software . ... We present a framework for modelling atmospheric phase errors and their correction by both the fast-switching and water vapour radiometeric techniques. Notable features are simulating three dimensional turbulent volumes instead of flat phase screens, considering three representative configurations of ALMA and parametrisation in terms of phase fluctuations on a 300m baseline, allowing referencing to the site-testing interferometer data. ...
