## Keyword descriptions

SECTION_PARAMETERS: string = DEFAULT

  Usage: H

  The name of the kind described in this section. [Edit on GitHub]

BASIS_SET: string = DEFAULT

  Usage: BASIS_SET H

  The name of the basis set for the kind. Has to be specified in BASIS_TEMPLATE_FILE. [Edit on GitHub]

INITIAL_DEGREES_OF_FREEDOM: enum = COEFFICIENTS

  Usage: INITIAL_DEGREES_OF_FREEDOM ALL

  Valid values:

  - `ALL` Set all parameters in the basis to be variable.

  - `NONE` Set all parameters in the basis to be fixed.

  - `COEFFICIENTS` Set all coefficients in the basis set to be variable.

  - `EXPONENTS` Set all exponents in the basis to be variable.

  Specifies the initial degrees of freedom in the basis optimization. This can be used to make further specifications easier [Edit on GitHub]

SWITCH_COEFF_STATE: integer[4]

  Keyword can be repeated.

  Usage: SWITCH_COEFF_STATE SET L CONTRACTION IPGF

  Allows to switch the state of a given coefficient from current state (varibale/fixed)) to the opposite state. The three integers indicate the set number, the angular momentum i’th contraction and i’th coefficient [Edit on GitHub]

SWITCH_CONTRACTION_STATE: integer[3]

  Keyword can be repeated.

  Usage: SWITCH_CONTRACTION_STATE SET L CONTRACTION

  Allows to switch the state of a given contraction from current state (varibale/fixed)) to the opposite state. The three integers indicate the set number, the angular momentum and i’th contraction [Edit on GitHub]

SWITCH_EXP_STATE: integer[2]

  Keyword can be repeated.

  Usage: SWITCH_EXP_STATE SET IEXP

  Allows to switch the state of a given exponent from current state (varibale/fixed)) to the opposite state. The two integers indicate the set number and i’th exponent [Edit on GitHub]

SWITCH_SET_STATE: integer[2]

  Keyword can be repeated.

  Usage: SWITCH_SET_STATE SET IEXP

  Allows to switch the states of in a set from current state (varibale/fixed)) to the opposite state. The two integers indicate the affected part (0=ALL,1=EXPS,2=COEFF) and i’th set [Edit on GitHub]
