The computer routine used in a previous paper [ J. Opt. Soc. Am. A 13, 523 ( 1996)] for the concatenation of eikonals is quite slow in certain demanding cases. This problem can be overcome by using the order doubling technique developed for this purpose by Forbes [ J. Opt. Soc. Am. 72, 1097 ( 1982); J. Opt. Soc. Am. 73, 782 ( 1983)] and Forbes and Andrews [ J. Opt. Soc. Am. 73, 776 ( 1983)] more than a dozen years ago. Numerical experiments show that this technique speeds up the calculations by two orders of magnitude or more.
