Abstract
A new four-colour photometric system is developed utilizing glass colour
filters but with bands somewhat narrower than in case of conventional broad
band photometry. The effective wavelengths of particular spectral bands are:
lambda = 3520; 3780; 4600; 5500 A. The measurements of 104 bright stars show
that this system is useful for two-dimensional classifications of unreddened
F and G type stars or for discrimination of subdwarfs irrespective of their
reddening. While being somewhat less accurate this system should have the
advantage of fainter limiting magnitude in comparison with other intermediate
band-width systems which have similar properties.
