In 1848 the Swiss astronomer Johann Rudolph Wolf introduced a daily measure- ment of sunspot number. His method, which is still used today, counts the total number of spots visible on the face of the sun and the number of groups into which they cluster, because neither quantity alone satisfactorily meas- ures sunspot activity. An observer computes a daily sunspot number by multiplying the number of groups he sees by ten and then adding this product to his total count of in- dividual spots. ...

Chaotic oscillators based on RC-elements and nonlinear amplifiers with sigmoid function only are discussed. The analysis of the structure a number of well-known oscillators is carried out. On the basis of that analysis the structure of the oscillators which consist of RC–elements and op-amps only and capable to show chaotic oscillations is suggested. ...
CLEAN Map ps -- is a plot of the naturally weighted CLEAN image. The lowest contour levels (2 steps) on image is plotted at "clev" levels [Jy/beam], the peak brightness -- "max" values [Jy/beam]. The dashed contours indicate negative flux. The beam is shown in the bottom left corner of the images. The plot is in postscript format.
