Manual fit refinements
Although HyperLab has an outstanding quality automatic deconvolution algorithm, it sometimes results in sub-optimal region fits.
This may be due to several reasons:
it may signal a problem with the quality of the measurement system (noisy amplifiers, improper pole-zero settings etc);
miscalibration of the FWHM values;
lack of a well-defined background (this may be the case when extremely complicated multiplets fitted, and no relevant background information is available);
and naturally minor existing bugs in HyperLab's complicated fitting algorithm.
The following sections deal with the most frequently occurring bugs and their suggested correction methods.
