1. VLBApls source sample
... The VSOP Survey Continuum Source List . The radio sample for the VSOP continuum survey was defined to include all extragalactic radio sources with: . a total flux density at 5 GHz, S>=1.0 Jy . ... The sample also included all sources in the sky with a 5 GHz flux density S>5 Jy, regardless of spectral index and galactic latitude. ... The source would then be included in the VSOP sample (three of the sources were found with a flux density above 1 Jy and added to the sample). ...

7. Weighting
... Each visibility sample is given a weight in the imaging step. ... However the synthesised beam-shape and sidelobe levels are usually poor. ... Uniform weighting (including super- and sub-uniform weighting) minimises sidelobes, whereas natural weighting minimises the noise level. ... Suppressing sidelobes over the entire field of the dirty beam corresponds to uniform weighting - that is, we get uniform weighting if sup is set to the field size of the dirty beam; this is the default. ...

... Samples of expected results from an intensive search for planets about stars acting as gravitational lenses (lens stars) of galactic bulge stars (source stars) during microlensing events are constructed. ... The Gould and Loeb (1992) detection probabilities are scaled to arbitrary planetary mass and mean lens distance and averaged over the lens mass function. ... The expected total number of planets detected depends entirely on the assumptions about the nature of the planetary systems being sought. ...

... One of the objectives of this work is to derive radial distribution of supernova remnant surface densities in spiral galaxies. ... Other objectives include the comparison of the SNR radial distribution with the radial distribution of HII regions to look for any association between Type II progenitors and the SNRs and comparison of the SNR distribution to the spiral arm patterns. ... Knowing the positions of the SNRs, we can compare their distributions relative to HII regions and spiral arms. ...
