  IM_TIME
  	IM_TIME {Logical}
  	Turns on cubic scaling RI-RPA and Laplace-SOS-MP2 method using the imaginary time formalism. If no IM_TIME section is present, default parameters are used.
  	This keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.
  	Alias names for this keyword: IMAG_TIME

  QUADRATURE_POINTS
  	QUADRATURE_POINTS {Integer}
  	Number of quadrature points for the numerical integration in the RI-SOS-MP2-Laplace method.
  	This keyword cannot be repeated and it expects precisely one integer.
  	Default value: 5
  	Alias names for this keyword: LAPLACE_NUM_QUAD_POINTS

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