Set here atom features related with structural analysis, using methods such as diffraction.

### Temperature

Set here the atom temperature. Temperature information is needed to calculate Debye-Waller temperature factors, which, together with structure factors, are needed to calculate accurate X-ray and electron diffraction patterns.

### Occupancy

Although by default all atoms have occupancy 1.0, many experimental results can only be explained assuming that some positions are not always occupied by the same type of atom. Therefore these atoms have an average occupancy between 1.0 and 0.0. Apart from the structural information in itself, carried in these occupancy factors, they are needed to accurately calculate the diffraction structure factors and the corresponding diffraction patterns in solids and liquids.
