Abstract: Based on multicolour observations of two contact systems with flat bottom minima, we investigate the consistency of derived photometric mass ratio parameters. Applying the Wilson-Devinney code, we derived the best solutions using the Monte Carlo search method for GSC 2723-2376 and GU~Ori. We found discrepancies in q_phot among our solutions and those previously published for the two systems, reaching more than 10%. This will lead to similar differences in the physical parameters.
