at.load.elegant#

Load a lattice from an Elegant file (.lte).

This is not complete but can parse the example files that I have. This parser is quite similar to the Tracy parser in tracy.py.

The Elegant file format is described briefly here. It is similar to the MAD-X format.

Note that Elegant scales magnet polynomials in a different way to AT, so the parsed coefficients need to be divided by n! for the coefficient of order n.
