R_FACTOR_TYPE

R_FACTOR_TYPE determines what definition of the \(R\) factor is used in \(R\)-factor calculations, including during the search. For details, see \(R\)-factor calculation.

Default: pendry

Allowed values: pendry (1), r2 (2), zj (3), smooth (4)

Syntax:

R_FACTOR_TYPE = smooth   ! equivalent: R_FACTOR_TYPE = 4

Warning

The “smooth” \(R\)-factor \(R_\mathrm{S}\) is currently only implemented for the Structure search using the viperleed-jax BACKEND. All segments except for the Structure search will default to \(R_\mathrm{P}\) when \(R_\mathrm{S}\) is picked, printing a warning.

Changelog

Changed in version 0.15.0: Added support for \(R_\mathrm{S}\)

Changed in version 0.15.0: Accepts string definitions in addition to integers
