An Automatic Spectrophotometric Data Reduction System for Quantitative Spectral Classification of Stars
Some years ago a complex programme of studying the main meridianal section of the Galaxy (MEGA = MEridian of GAlaxy) was started to improve our knowledge about spacial and kinematical characteristics of stellar populations. The tasks and the present state of the MEGA program has been described recently by Malyuto, Einasto, Kharchenko and Schilbach (1990). The use of absolute proper motions of stars (with respect to galaxies), photoelectric UBVR and Vilnius photometry together with automated quantitative spectral classification for large stellar-statistical samples are among the most essential features of the programme. The data are gathered in 47 areaswithin 30° from the main meridional section of the Galaxy.
