The following general subroutines belong to the category CONVOLUTION:
``Convolution of data'' In parentheses the name of the source file is given.

CONPVARS: Determine parameters of 2d-gaussian needed to convolve 'oldbeam' to 'newbeam' (convpars.shl)
FILLGAUSS2D: Fill array with values of (rotated) 2-d Gauss (fillgauss2d.c)
PRESMOOTH: Calculate convolution function parameters for use in smoothing to a bigger (rotated) beam and determine scale factor to be able to preserve definition of brightness temperature. (presmooth.shl)
