An element that rotates the beam about the longitudinal axis.
Parallel capable? : yes
GPU capable? : yes
Back-tracking capable? : yes
| Parameter Name | Units | Type | Default | Description |
| TILT | RAD | double | 0.0 | rotation about longitudinal axis |
| EXCLUDE_FLOOR | short | 0 | if non-zero, does not affect the floor coordinates |
|
| EXCLUDE_OPTICS | short | 0 | if non-zero, does not affect the optics (i.e., transfer matrix is unit matrix) |
|
| 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 |

The sign convention for the TILT parameter is confusing on this element. In particular, a positive TILT rotates the beam counter-clockwise about the longitudinal axis. This is the opposite sense to rotations of elements, where a positive TILT rotates the element clockwise about the longitudinal axis.
Hence, if one wanted to rotate a series of elements by 0.1 rad, one could do the following:
The TILT value for ROT1 is the same (including the sign) as the individual TILT values one would give to all the elements represented by ....
