Examples

Freeze one or more parameters. Use Asterix list syntax to specify the parameter numbers.

  OPTION - ... > F
  PARS - Enter component numbers > 1:3
 
  OPTION - ... > F
  PARS - Enter component numbers > 4:*
Thaw one or more parameters
  OPTION - ... > T
  PARS - Enter component numbers > 3,2,7:8
Create new model
  OPTION - ... > NM
  A composite model can be synthesised using + - * ( ) and
  any of the following primitive models:
  AG     galactic interstellar absorption             multiplicative
  ..     ...                                          ...
  LL     Lorentzian line                              additive
  MODEL_SPEC - Model specification > AG*PL
List existing model
  OPTION - ... > L
Alter parameter values
  OPTION - ... > A
  PAR - Enter component number > 3
  VALUES - New values /'none'/ >
none leaves the values unchanged. 1 value is parsed as the new parameter value, 2 values as the new lower bound + new value, and 3 values as new lower bound, new value, new upper bound.
