## Keyword descriptions

SECTION_PARAMETERS: logical = F

  Lone keyword: `T`

  Usage: &RI_SOS_MP2 .TRUE.

  Putting the &RI_SOS_MP2 section activates RI-SOS-MP2 calculation. [Edit on GitHub]

NUM_INTEG_GROUPS: integer = -1

  Usage: NUM_INTEG_GROUPS 2

  Number of groups for the integration in the Laplace method. Each groups processes the same amount of quadrature points. It must be a divisor of the number of quadrature points and NUM_INTEG_GROUPS*GROUP_SIZE must be a divisor of the total number of processes. The default (-1) is automatic. [Edit on GitHub]

QUADRATURE_POINTS: integer = 5

  Aliases: LAPLACE_NUM_QUAD_POINTS

  Usage: QUADRATURE_POINTS 6

  Number of quadrature points for the numerical integration in the RI-SOS-MP2-Laplace method. [Edit on GitHub]
