CrysAlisPro 1.171.40.53 (Rigaku Oxford Diffraction, 2019).
Numerical absorption correction based on gaussian integration over
a multifaceted crystal model. Empirical absorption correction using
spherical harmonics, frame scaling and detector area scaling,
implemented in SCALE3 ABSPACK scaling algorithm.
