Some comments on the paper "Filter design for the detection of compact   sources based on the Neyman-Pearson detector" by M. Lopez-Caniego et. al   (2005, MNRAS 359, 993)
  In this note we stress the necessity of a careful check of both the theoretical arguments and the numerical experiments used by Lopez-Caniego et al. (2005) to support the superior performances of the biparametric scale adaptive filter (BSAF) with respect to the classic matched filter (MF) in the detection of sources on a random Gaussian background.
