 INP       1    UNIV        Input data (either a single
                            dataset or a file of
                            references).
        -GLOBAL.FIT_DATA (Default parameter dataset)
 Z         -    REAL        Source redshift
        -GLOBAL.REDSHIFT (Default redshift parameter)
    Default = 0
 MODEL     2    UNIV        Data object containing model
                            specification.
        -GLOBAL.FIT_MODEL (Default model dataset)
 LIK       -    LOGICAL     Likelihood(Y) or chi-squared(N) fit?
    Hidden default = NO
 PARS      3    INTEGER     Array of parameter numbers, one for
                            each grid axis. See examples.
 ERR       -    LOGICAL     Use parameter errors to define default
                            for AXIS1..7 ranges.
    Hidden default = NO
 AXIS1..7  -    CHARACTER   Range of parameter value for
                            each grid axis. Default is
                            current parameter range.
 NBIN1..7  -    INTEGER     Number of bins for each grid axis
 OPT       -    INTEGER     Option for specifying grid axis
    Default = 1             bin spacing. Can be 1 = all linear,
                            2 = all logarithmic, 3 = user
                            selects for each axis.
 LOG1..7   -    LOGICAL     Logarithmic or linear for each
                            grid axis. Only used ifg OPT=3.
    Default = NO
 GPARS     -    INTEGER     List of values to grid. See examples
    Default = 0
 MAX       -    INTEGER     Max number of iterations to be
                            performed. Only used if grid
    Default = 30            leaves free parameters.
 MINS      -    REAL        Minimum reduced chi-squared gradient
                            for termination. Only used if grid
    Hidden default = 20.0   leaves free parameters.
 AUTO      -    LOGICAL     Automatic naming for multiple
                            output files.
    Default = YES
 OUT       -    UNIV        Output filename for 1st grid
    -> GLOBAL.BINDS (Default binned dataset)
 OUTROOT   -    CHAR        Root filename for automatic naming
 OUT2..5   -    CHAR        Output filenames for each grid. Only
                            used if AUTO is specified false.
 SUBSTAT   -    LOGICAL     Subtract minimum value of statistic
                            from statistic grid. Only used if
    Default = NO            GPARS contains a 0 in the list.
 UP        -    LOGICAL     Update the model with the best fit
                            parameter set?
    Hidden default = NO
