... 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. ...

... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

Fabry-Perot data cubes. Introduction: what is "data cubes"? Observations with the IFP consist of successive acquisition of a few dozen images of interference rings from the object (or from a calibration lamp) when changing the optical path between the flat-parallel plates. The radius of the rings is a function of wavelength and gap between the plates of the interferometer. ... Its interference rings of Ne line which use for phase calibration (convert object data to wavelength-scale). ...
