15. Conclusions Prospects Further improving of coordinate and photometric support of catalogues of specific stellar data (spectral, RV, etc.) Completion of SuperCOSMOS catalogue GSC II  GSC 2.3 Problems: Cross-identification of objects at different epochs Absence of deep all-sky multi-vawelength photometric standards
