... Previous: Image Processing of Digitized Spectral Data . ... The analysis of sequences of light curves spanning a long time interval (at least one or two decades) allows us to detect activity cycles, analogous to the solar 11-year cycle, inferring the overall properties of the stellar dynamos. ... Our parallel procedure was written in standard FORTRAN using the PVM library version 3 and exploits a networked system to perform the analysis of a sequence of N L light curves. ...

... W. Steffen , T.P. Krichbaum , S. Britzen and A. Witzel . ... Such oscillations can result from precession of the jet, helical magnetic fields, or helical instabilities. ... VLBI monitoring of the milliarcsecond scale structure shows stationary components at about 5, 1.4 and 0.4 mas separation from the core ( Eckart et al. ... The accumulated VLBI data show that the observed components and the continuous jet structure are aligned along a curved, oscillating ridge line (see Figure 1 ). ...
