FIT Sub-Menu Commands

CHANGE SCALE Change the typical parameter variation sizes
CLEAR MASK Eliminate all masked-off ``bad'' data points
CONSTRAIN Set constraints, change parameters values
COVARIANCE Output covariance matrix
DEFINE MASK Mask-off ``bad'' data prior to fitting
DISPLAY MASK Display masked-off data as a two level image
EXIT Exit fit sub-menu
INPUT PARAMETERS Initialisation of fit model
MASK STATISTICS Statistics of mask
MINIMISE Search for better fit by maximum descent method
MODEL Create fit model (in memory) from current parameter values
NORMALISATION Uni-directional flat-field normalisation
OUTPUT PARAMETERS Output fit parameters to a file
POWDER DIFFRACTION Fit beam centre and tilt to powder ring
QUIT Exit fit sub-menu
R/THETA RE-BINNING Radial/Angular (polar) re-binning of ROI
RADIAL PROFILE Calculate 1-D radial profile in memory
RESULTS View results of fitting
SET MASK COLOUR User choice of colour to draw masked pixels
SET UP Alter fit control parameters
SURFACE POLYNOMIAL Fit data using 2-D Chebyshev polynomial
THRESHOLD MASKING Mask elements depending on ROI data values
TILT/BEAM CENTRE Determine from a powder ring
TRANSFER MASK TO MEMORY Set masked elements to 1.0 in memory
