... What work is currently being done to improve the flux calibration accuracy for echelle modes? ... Starting early in Cycle 11, monthly offsetting for echelle modes was turned off to minimize these types of calibration problems. ... We are currently working on redetermining the echelle flux calibration so that it is self-consistent with the 2-D scattered light algorithm. Time dependence of the sensitivity - Sensitivity-monitor data for the echelle modes are currently under investigation. ...

. 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 .

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. ...
