Abstract
It is shown that the use of an ensemble of reading heads of a certain format, consistent with the parameters of the measuring raster and the matrix of indicator rasters in readheads, can significantly reduce the distorting effect of the systematic component of the instrumental error of the raster. It is noted that the specific technical solution considered in the present paper for matching the parameters of complementary lattice filters is not the only one for the raster used.
