The collisions between atoms in a spectral tube can be one of important Sources of emission-line broadening.

We find a total of 100 emission-line objects, of which 96 are galaxies, the rest being 3 planetary nebulae and 1 star.

This paper is the fourth in a series publishing the results of an objective prism survey for emission-line galaxies with the 60 cm Schmidt Telescope of the Beijing Astronomical Observatory.
