Detailed Description

Structure defining a fit parameter in the FITPARAMETER block.

This structure contains all information about a single fit parameter: its number, name, value, uncertainty, and optional constraints (boundaries). Parameters can be fixed (fStep=0) or free (fStep>0), and may have asymmetric errors after fitting.

Example MSR line: "3 alpha 1.0 0.1 0.5 1.5" defines parameter #3 named "alpha" with value 1.0, step 0.1, and bounds [0.5, 1.5].
