Correction: MN15: A Kohn-Sham global-hybrid exchange-correlation density functional with broad accuracy for multi-reference and single-reference systems and noncovalent interactions. [PDF]
We report a global-hybrid approximation, MN15, to the exchange–correlation functional of Kohn–Sham theory with broadly accurate performance for both multi-reference and single-reference systems.

Independent analysis of μδ data of ILS and INDLS catalogs to obtain the spin of the bright Gaia DR2 reference frame [PDF]
The Gaia DR2 reference frame should be without relative rotation to the quasars (QSOs) and consistent with the International Celestial Reference System (ICRS).

Corrections to the Hipparcos proper motions in declination for 807 stars [PDF]
We used the data on latitude variations obtained from observations with 10 classical photographic zenith tubes (PZT) in order to improve the Hipparcos proper motions in declinations µδ for 807 stars.

Photographic zenith tubes observations to improve HIPPARCOS proper motion in declination of some stars [PDF]
A procedure of calculation and results of an attempt to improve proper motions in declination for some HIPPARCOS stars are presented. A long series of optical observations of these stars observed with Photographic Zenith Tubes (PZT) are used.

Spherical trigonometry of the projected baseline angle [PDF]
The basic vector geometry of a stellar interferometer with two telescopes is defined by the right triangle of (i) the baseline vector between the telescopes, of (ii) the delay vector which points to the star, and of (iii) the projected baseline vector in

Earth orientation and its excitations by atmosphere, oceans, and geomagnetic jerks [PDF]
In addition to torques exerted by the Moon, Sun, and planets, changes of the Earth orientation parameters (EOP) are known to be caused also by excitations by the atmosphere and oceans.

Astrometric star catalogues as combination of Hipparcos/Tycho catalogues with ground-based observations [PDF]
The successful ESA mission Hipparcos provided very precise parallaxes positions and proper motions of many stars in optical wavelength. Therefore it is a primary representation of International Celestial Reference System in this wavelength.
