... Accurate identification of physical binary star systems has become of increasing interest in recent years. ... Identification of physical binary star systems, with an estimated reliability of such identifications based on the theory of probability, is also important for current and future efforts to find binary star systems that are candidates for observations with the aim of determining their orbits and component masses. ... probability of the proximity of proper motions and ; . ...

... The software systems are described following the forward and back­ ward data flow to/from the satellite: starting from the Observation Pro­ posal reception and archiving, the long term observation scheduling up to the detailed weekly planning and telecommands sequence uplinking, and vice versa the scientific and housekeeping raw telemetry acquisition and archiving, quick look data analysis, data reformatting and distribution as a Final Observation Tape to the Observation Proposal PI. ...

IRAF/STECF 2-D spectrum point source / background decomposition package . ... The general problem is one of spectral decomposition - of separating the spectra of the point sources from the background. ... The STECF IRAF layered package "specres" provides two tasks to extract point source spectra from 2-D images (either longslit, multislit or cross-dispersed) and decompose the full background over the image. ... A Point Source Function spectrum image is required as a 2-D spectrum. ...
