Parameter Name	Units	Type	Default	Description

L	M	double	0.0	length

TILT	RAD	double	0.0	rotation about longitudinal axis

DX	M	double	0.0	misalignment

DY	M	double	0.0	misalignment

DZ	M	double	0.0	misalignment

FILENAME		STRING	NULL	name of file containing talor series map data

GROUP		string	NULL	Optionally used to assign an element to a group, with a user-defined name. Group names will appear in the parameter output file in the column ElementGroup

This element allows transforming the beam using an arbitrary polynomial in the six phase space coordinates, x, q_x, y, q_y, s, and δ. Please note that the canonical momenta are used here, not the slopes.

The input file is required to have six pages, each of which gives the polynomial for a different output coordinate. The file has the following elements:

String parameter Coordinate names the output coordinate. The file must contain a page for each coordinate, using the names x, qx, y, qy, s, and delta.
Integer columns Ix, Iqx, Iy, Iqy, Is, and Idelta, which give the exponent to be used for the indicated coordinates.
Floating-point column Coefficient giving the coefficient by which to multiply the product of powers of the coordinates. I.e., the term is Cx^Ixq_x^Iqxy^Iyq_y^Iqys^Isδ^Idelta

Note that in the present version, dependence on s is actually ignored.
