Description:
    Table 2 contains the results of photometry of 948 stars down to
    V=16.2mag in the Vilnius seven-color system at the North Ecliptic
    Pole. Photometric data are used to classify about 500 stars in
    spectral and luminosity classes. For the remaining stars
    one-dimensional spectral classes are given. The results of photometry
    and classification can be used to supplement the catalog of Gaia
    standard stars near the Ecliptic poles. To facilitate this, Table 3
    presents the magnitudes of the SDSS and Gaia systems transformed from
    the Vilnius seven-color photometry.
