... A Multidimensional Binary Search Tree for Star Catalog Correlations D. Nguyen, K. DuPrie and P. Zografou Smithsonian Astrophysical Observatory, Cambridge, MA 02138 Abstract. A multi­dimensional binary search tree, k­d tree, is proposed to support range queries in multi­key data sets. ... Data Volume Limitation If the k number of keys to be searched for contain RA, Dec and some other attributes then one can minimize the number of nodes in the tree by utilizing only the near neighbor FITS files. ...

STANDART (ZONE) TIME is a medium solar time, determined for the 24 general geographical meridians, being 15* in longitude. The Earth surface is divided into 24 hour zones (with numbers from 0 to 23) where zone time coincides with the time of the prime meridian passing through these zones. ... The zone time of some zones has it’s own name, for example the zone time of the zero zone is called West – European (universal); the zone time of the second zone is called East-European. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
