... Since the bulk of the data for rotational modulation were taken during short ( < 11 night) runs, there is a great deal of variation in the sensitivity to periods, depending on the length of the period. The searches are much more sensitive to short periods than to longer ones. ... For the simulation, the input data was a pure sine wave. ... The strength is that in all cases, even down to signal to noise levels of one, a large percentage of the power can be found in the correct period. ...

To the IUM main page . The finite-gap solutions of the Sine-Gordon equations were constructed about 20 years ago. One of the main characteristic of these solutions is the topological charge and it is natural to pose the problem of calculating it in terms of the spectral data. A formula for the spectral charge was suggested by Dubrovin and Novikov, but they proof was based on an assupmtion about the divisor behaviour, which is correct only in a neighbourhoood of degenerate curves. ...
