Next: Echelle Reduction Up: No Title Previous: CCD-Commands Summary . The reduction of CES spectra is, especially for point sources, very straightforward, and the general instructions given in Chapter 6 for the standard reduction of spectra are fully adequate. ... As far as the data reduction goes, the main difference between Reticon and CCD is the data format. Since the Reticon is a one-dimensional array, no attention has to (can) be paid to the extraction of the object spectra. ...

Next: A Universal Diagram for Up: ``Ecology'' of Magnetic Rotators Previous: The Corotation Radius . The interaction of a magnetic rotator with the surrounding plasma to a large extent depends on the relation between the four characteristic radii: the stopping radius, , the gravitational capture radius,   , the light cylinder radius,   , and the corotation radius,   . ... Hence, the classification of the interaction regimes may well mean the classification of magnetic rotators. ...
