       Necessary  input  are: Several (usually 75) raw frames classified as FIBRE_NS Standard (an
       ´ON´ and an ´OFF´) flat frames having classified as  FLAT_NS  Standard  (an  ´ON´  and  an
       ´OFF´)  arc  lamp frames having classified as WAVE_NS A corresponding (band) reference arc
       line list classified as REF_LINE_ARC A reference  table  with  data  reduction  parameters
       classified as DRS_SETUP_WAVE.
