The MUNICS project is an ongoing imaging survey designed to cover 3 sq. degrees in V,R,I,J,K'. We describe here partial results of the project concerning the clustering properties of K' < 19.5 galaxies in scales of 3.6'' to 63.0'' over an area of ∼ 800 arcmin2. We present K' data for a sample of 20 fields, five of which contain z > 0.5 radio-loud quasars with steep spectra, eight contain z > 0.5 radio-loud quasars with flat spectra and seven are high-galactic latitude fields with no quasars in them. The two-point angular correlation function for the total sample shows significant clustering at ∼ 5 σ level of K'=19.5 galaxies. The correlation angle of the galaxies is θ0 = 1.7'' ± 0.4'' for K' < 19 mag and θ0 = 1.0'' ± 0.2'' for K' < 19.5 mag. When the correlation functions for the subsamples are considered, the mean ω(θ) amplitude of the fields which contain steep-spectra z > 0.5 radio-loud quasars is determined to be ∼ 2.0 - 2.5 that of the high-galactic latitude fields.
