... As of October 1, 2009, the global rate for the STIS NUV-MAMA dark current has still been occasionally reaching values as high as 13500 counts/s. This high dark current will force use of a signficantly smaller buffer time than would be otherwise needed, and in many cases may push the count rate high enough to make time-tag observations impractical. ... However, we instead found for the NUV MAMA detector an initial global dark rate of between 9000 and 18000 counts/s (a mean of 0.013 counts/s/pixel). ...

A fifth telescope was sited on the Southwest arm of the COAST array. ...

Next: Modes of Operation Up: CCD Scientific Performance Previous: Field of View . Thermal excitation of charge carriers from the valence to the conduction band creates a dark current signal which may vary with position in the array, and also has temporal shot noise variation. ... In a device devoid of localized defects which give rise to individual dark current spikes , most dark current arises from electrons generated at interface states at the surface. ...

As noted earlier Kristian Birkeland, reporting in 1903 on his expeditions to the auroral zone, proposed that magnetic disturbances accompanying the aurora were caused by large electric currents flowing down the length of auroral formations. ... Some scientists disagreed with Birkeland and claimed the electrojets did not connect to space but instead their entire circuit lay inside the ionosphere, like that of other ionospheric currents known at the time, believed to be caused by atmospheric tides. ...

As noted earlier Kristian Birkeland, reporting in 1903 on his expeditions to the auroral zone, proposed that magnetic disturbances accompanying the aurora were caused by large electric currents flowing down the length of auroral formations. ... In later years these currents became known as the auroral electrojets , and considerable debate ranged over their cause and the way their circuit might be completed. ...

. The following is a list of the currently installed versions of the CIMA. The links refer to the CIMA version log page . Normal: version 3.0 - this is the next version of CIMA which has become the new default version --- NOTE that this version uses a new syntax for command file observations, uses new configuration files and needs source files with full velocity information . Old: version 2.2 - this is the old version of CIMA You can return to the main CIMA page by clicking here .

Parkes Counterweight Issues May 4, 2002 1 Background It became clear, during the course of the study of the windloading on the Parkes reflector (ref: AT/39.3/113) that the counterweight was not optimally fulfilling its function. ... Figure 1: The elevation motor currents as a function of the elevation. ... If the weight is positioned below the current centre of mass (32 cm south of the elevation axis), then the horizon current doubles to 8 A; the peak current (at El0 increases by 0.3%. ...
