ON THE IMPACT OF THE GALACTIC ABERRATION ON VLBI-DERIVED PRECESSION MODEL Z.M. MALKIN Pulkovo Observatory Pulkovskoe Ch. ... Corrections to adopted precession rate are usually computed from the linear trends in long-term time series of celestial pole offset (CPO), which are the differences between the measured and the theoretical coordinates of the celestial pole. ... CONCLUSIONS We have estimated the impact of GA on parameters of precession-nutation model derived from VLBI observations. ...

... The large body of near infrared observations presented in Testi et al. (1997; 1998) are analysed with the aim of characterizing the young stellar clusters surrounding Herbig Ae/Be stars. The results confirm the tendency of early Be stars to be surrounded by dense clusters of lower mass "companions", while Ae stars are never found to be associated with conspicuous groups. ... Only the most massive stars (10-20Msun) are found to be associated with dense (10^3 pc^-3) stellar clusters. ...

... Old World First Asteroid Radar Echo. ... It testifies that 4179 Toutatis is a double object like asteroid 4769 Castalia. ... Interference of Radar Echo from the Binary Asteroid 4179 Toutatis. ... An analysis of the 6-cm radar data revealed quasi-harmonic oscillation of the echo’s “central” Doppler frequency with a period of about 14 sec and a deviation of about (0.7*B) Hz, where B is the echo bandwidth, which for 4179 Toutatis was equal to 2.1 Hz and 1.9 Hz for 1992 Dec 8 and 9, respectively. ...

... Archives . ... On the other hand, CHASC scientists relate more general and broad statistical inference problems in estimating the intensity map, like intensity uncertainties at each point and the scientifically informative display of the intensity map with uncertainty according to the Poisson count model and constraints from physics and the instrument, where the field, multiscale modeling is associated. As the post title [MADS] indicates, no abstract has keywords multiscale modeling. ...

The unification and synchronization of data-flows from these telescopes will allow one to carry out astronomical observations at a new level and to realize a virtual observatory with new capabilities for space research. ...

... In addition to time, frequency, and scale, there are two other coordinate axes within this transform space: shear-in-time (obtained through convolution with a q-chirp) and shear-in-frequency (obtained through multiplication by a q-chirp). Signals in this multidimensional space can be obtained by a new transform which we call the ``q-chirplet transform'', or simply the ``chirplet transform''. ... CHIRPLET TRANSFORM SUBSPACES . ...
