  QUADRATURE_POINTS
  	QUADRATURE_POINTS 60
  	Number of quadrature points for the numerical integration in the RI-RPA method.
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 40
  	Alias names for this keyword: RPA_NUM_QUAD_POINTS

  SIZE_FREQ_INTEG_GROUP
  	SIZE_FREQ_INTEG_GROUP 16
  	Group size for frequency integration, that is the number of processes involved in the computation of each integration point. SIZE_FREQ_INTEG_GROUP has to be a multiple of GROUP_SIZE in the WF_CORRELATION section. The default (-1) is automatic.
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: -1
  	Alias names for this keyword: RPA_GROUP_SIZE
