Description Usage Arguments Value Examples
The unit cell side is roughly calculated by adding two times the half-width of the widest gaussian atom to the largest inter-atomic distance. The half-width of the largest gaussian is computed as Ma times the gaussian sigma. If the "P-1" symmetry is present, D is doubled.

Z |
A vector of atom Z numbers. |
D |
A real number. The distance between the two furthest atoms in the cell. |
SG |
2-letters character string. Symmetry. There are only two symmetries possible when working within 1D crystallography, P1 (no symmetry)and P-1 (inversion through the origin). SG can be either "P1" or "P-1" for this function. |
k |
A real number. It controls the standard deviation of the
gaussian function describing the atom and, thus, the shape of the
associated peak. The standard deviation sigma is given by:
|
Ma |
A real number. Each gaussian atom has tails truncated at a distance of Ma * sigma from its peak. |
A real number that suggests a feasible unit cell side containing all atoms.
