$\displaystyle LULTRA =$   use ultrasoft PP$\displaystyle \qquad F \vert T

Default : .FALSE.

Determines, whether US pseudopotentials are created. The calculation of the US pseudopotentials is not done within rhfsps but within fourpot3. Actually for LULTRA=T, simply two sets of pseudo wave functions per l-quantum number are calculated. The first set is used by fourpot3 to set up the augmentation part, and the second pseudo wave function is used for the actual pseudopotential description.
