Case history of the use of fan filtering for improving reflection continuity without destroying their character. The field technique is described: wide‐band, large dynamical range recording with a programmed gain control and a very slow A.G.C., small distance between trace centers, high cutoff wave‐number. Although the total amount of mixing due to fan filtering is rather high, a broad spectrum was obtained and inverse convolution filtering was used to improve trace resolution.
