Next: CCD data Up: Special problems Previous: Marginal nights . If the program complains that you have negative intensities, this is usually due to misidentifying star observations as sky. ... Another problem with sky occurs when the program cannot find a suitable sky observation to subtract from a star datum. ... Finally, as the sky-modelling algorithm does not try to model twilight, it uses the ``nearest-neighbor'' method to correct star observations made during twilight for sky. ...

For each source that is to be used as a reference source the user needs to: . ... There is an alternative reference source input method available that is activated with the withrefsrclist parameter. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ...

The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...
