We derive accurate, homogeneous atmospheric parameters (Teff , log g, Vt, [Fe/H]) for 74 FGK non-variable supergiants and for 30 classical cepheids in 302 pulsation phases based on the highresolution, high signal-to-noise echelle spectra. The extreme

The accuracies of some selected stellar catalogues of Teff values have been estimated through data intercomparison. The technique of such estimating developed earlier for triples of catalogues has been adapted to a set of catalogues. A homogenized ca

We considered some selected published stellar catalogues with B – V and V values for the open cluster NGC 188 and estimated the errors from data comparisons. The results are used to homogenize the data by averaging with weights inversely proportion

Homogeneous independent subsamples from selected catalogues and libraries of effective temperatures for metal deficient F–G stars are treated here by combining them in triples and pairs for the stars in common to determine their external errors fro

Astrometric observations at different zenith distances have been performed in Dresden in an area centered atNGC 6791 where there are some stars with reliable color information (widely dispersed spectral types in the MK systemand color indices BT –

A modification of the minimum distance method (or template matching) of classification has been tested where a maximum likelihood procedure is added. This two-stage combined method provides continuous classification with smooth linear interpolation.

We have simulated a set of “observed” spectra by combining synthetic 20 A resolution spectra (Kurucz models) with random variables drawn from the standard Gaussian distribution. The simulated spectra have been classified using Cayrel’s perturba

In ground-based measurements of exact posi- tions of celestial objects on the sky the astronomical at- mospheric refraction should be taken into account. In our calculations for refraction we use the Stone code (Stone 1996) where the mean refraction
