Abstract . Th e us e o f CC D detector s generate s a nee d for elaboratio n o f programme s for re ductio n o f astronomica l digita l images . Zeema n spectr a observe d wit h echell e an d long-sli t spec trograph s ar e a specia l sor t o f suc h images . Th e reductio n o f Zeema n spectr a ha s a numbe r o f specific peculiaritie s whic h ar e no t provide d i n standar d spectra l dat a reductio n programmes . I n thi s articl e w e describ e a se t o f programme s for th e reductio n o f Zeema n spectra . Th e programme s hav e bee n designe d a s a ES O MIDA S context .
