B-factor (a.k.a. Debye–Waller factor (DWF), temperature factor) relates to the fact that at higher temperatures, atoms will displace from their mean position more.
For example:
- in atomic structures, each atom may have a B-factor (as e.g. in PDB structures[1])
- in X-ray scattering, temperature factor will mean the peak will be lower
- in Transmission EM images, it will bias away from high frequency information
