The Southern Vilnius Photometric System. IV - The E region standard stars
This paper is the fourth in a series on the extension of the Vilniusphotometric system to the Southern Hemisphere. Observations were made of60 stars in the Harvard Standard E regions to increase a set of standardstars.

Photometric reductions and the lightcurve of (51) NEMAUSA
The light curve of the minor planet (51) Nemausa is derived on the basisof 1779 photoelectric (B and V) observations and a photometric reductionusing a rigorous least squares method. Separate light curves are givenfor the B and V observations, respectively. An absolute B-V magnitudefor (51) Nemusa of 0.787 + or - 0.004 mag was estimated. A detaileddescription of the least squares method is presented.
