18.34.11      MAP_CONVOLUTION

MAP_CONVOLUTION Integer

Select the desired convolution function for gridding in the UV plane Choices are

         0    Default (currently 5)
         1    Boxcar
         2    Gaussian
         3    Sin(x)/x
         4    Gaussian * Sin(x)/x
         5    Spheroidal

Spheroidal functions is the optimal choice. So we strongly discourage use of any other convolution function, which are here for tests only.
