Summary of reduction options

  The two following diagrams summarise the successive steps performed by high-level procedures RESPONSE/ECHELLE and REDUCE/ECHELLE depending on the main options:

• Flat-field correction can be performed or not
• Instrumental response correction can be skipped, or performed using either a standard-star or IUE-like methods.
