Module spectrum 

Spectrum file parser for TOF/energy bin edges or centers.

Parses CSV/TXT files containing TOF or energy values that define the spectral bins of a neutron imaging dataset.

Supported formats

• Single-column: one value per line
• Two-column (CSV/TSV): first column used, rest ignored
• Comment lines starting with # are skipped
• First non-comment line skipped if it cannot be parsed as a number (header)

Enums

SpectrumUnit

Whether spectrum values represent TOF or energy.

SpectrumValueKind

Whether values are bin edges (N+1 for N bins) or bin centers (N for N bins).
