Using a FORTRAN program on an IBM 7094, a tape was generated for off-line use on an SC 4020, which made the plot. The plotting subroutine interpreted a matrix as the dependent height variable. An angle of 40 degrees was specified, and hidden lines were tested for and removed. The figure is generated by sums of Gaussian functions.
