 SET UP

Various aspects of the minimisation may be controlled from this sub-menu. Most importantly are the number of iterations MINIMISE will perform before stopping, and the aimed accuracy of the fit. (Many of the options are not presently relevant since they refer to multiple 1-D fitting which is not presently implemented.)

The available options are:

ACCURACY: Set aimed accuracy of the minimisation process. This is the aimed for reduced chi-squared for a weighted fit, or the average square residual for an unweighted fit.

CHANGE FIT ORDER: Not relevant

DISPLAY FREQUENCY: Not relevant

EXIT: Exit from SET UP sub-menu to return to FIT sub-menu

FAST DISPLAY: Not relevant

HALT CRITERION: Not relevant

MAXIMUM LIKELIHOOD: Not relevant

MODEL EVOLUTION: Not relevant

NUMBER ITERATIONS: Set number of iterations per variable parameter

POISSONIAN STATISTICS: Not relevant

REQUEST CONTINUATION: Not relevant

VIEW: Display current state of all set-up variables

WEIGHTED FIT: Toggle between weighted, or unweighted fit (only relevant if variance arrays are present, otherwise all fits are unweighted)
