def create_image_table(self, r=None):
logger.info("<STR_LIT>")<EOL>if r is not None:<EOL><INDENT>self.r = r<EOL><DEDENT>self.image_table = ImageTable(self)<EOL>
Create and store a new ImageTable instance based on the current
        Dataset. Will generally be called privately, but may be useful as a
        convenience method in cases where the user wants to re-generate the
        table with a new smoothing kernel of different radius.

        Args:
            r (int): An optional integer indicating the radius of the smoothing
                kernel. By default, this is None, which will keep whatever
                value is currently set in the Dataset instance.
