x, y, z
Set the cell origin, always defined as the position of the node (000).
For
conventional,
primitive,
wigner and
rhombus volumes, the origin is initially at the lower-left
corner. For
sphere and
projection volumes, the origin
is initially at the center. When the volume is
projection,
the origin cannot be changed.
Example: <cell ... x="0.0" y="0.0" z="0.0"/> (default)
(defined in GAMGI_MESA_CELL_X, GAMGI_MESA_CELL_Y and GAMGI_MESA_CELL_Z)
Allowed values: real (optional, coupled)
e1, e2, e3
Set the three Euler angles controlling the cell orientation. The first
rotation (e1), around the initial y axis, must be between
0
and
180 degrees. The second rotation (e2), around the initial
z axis, must be between
0 and
360 degrees. The third rotation
(e3), around the final z axis, must be between
0 and
360.
By default (e1, e2 and e3 equal to zero), the first crystallographic
vector is aligned along the x-axis, the second vector lies above, on
the x-y plane, and the third vector has a positive z coordinate, thus
pointing to the user (right-handed orientation).
Example: <cell ... e1="0.0" e2="0.0" e3="0.0"/> (default)
(defined in GAMGI_MESA_CELL_E1, GAMGI_MESA_CELL_E2 and GAMGI_MESA_CELL_e3)
Allowed values: e1: 0.0 - 180.0, e2, e3: 0.0 - 360.0 (optional, coupled)
