Post-processing of a noisy BBMT record acquired in Buryatia, Southeastern Russia: a, b removal of the estimations obtained at frequencies characterized by increased sensor noise; c, d removal of the estimations obtained for the time frames (marked with different colors) characterized by high data scatter; e, f removal of the outliers and biased data to get smooth curves consistent with the DR-II
