The Mass Function of Dark Halos in Sup erclusters and Voids E. P. Kurbatov1 1 ,* Institute of Astronomy of the Russian Academy of Sciences A mo dification of the PressSchechter theory allowing for presence of a background large-scale structure (LSS) a sup ercluster or a void is prop osed. The LSS is accounted as the statistical constraints in form of linear functionals of the random overdensity field. ... Variance as a function of mass for different sets of constraints. ...

... We present a simple, e#ective technique that allows the con temporary spectroscopy of all the objects, up to a limiting magnitude, contained in a # 100 arcmin 2 field. This technique makes possible the immediate and unambiguous identification of peculiar objects included in the field. ... We show that this technique should also be quite useful in emission line and WR star surveys, and illustrate the software procedures devel oped to make the wavelength and flux calibration of these spectra. ...
