The contour data is given in a text file in MOVIE.BYU format. For each contour, there is a header line giving the number of points on the contour (I10 format), the z level of the contour (E12.5 format) and a label for the contour. This header line is followed by pairs of x, y coordinates for each point on the contour. There are 3 points on each line of the file. The point format is E12.5 for each coordinate.
