SETUP : For service mode observations within the SOLARNET Access Program, ROSA and IBIS can be utilized either as stand alone instruments, or combined together. ... PROPOSAL STRUCTURE: Proposals should include up to max 2 pages, including a scientific rationale and technical requests (detailing i.e. spectral filters and wavelength sampling). ... For the case of joint IBIS and ROSA observations, proposals should indicate which instrument is to be considered as the primary one. ... SOLARNET Access . ...

... They were determined as a result of orbit improving on the base of all kinds of optical observations available in the catalog of observations of the Minor Planet Center on March 16, 2014 (radar observations have not been used at this stage). ... As the MPC orbits do not all were improved simultaneously with EMP orbits, only 383866 sets of elements were used for data comparison (for selected sets of elements process of improvement had started with the use of the same observations). ...

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...
