Type
Mandatory Section#9 (Limb-Viewing only)

Description
Field of View function
This section is omitted for nadir-viewing spectra (as determined by the .l1c file).

Format
Single field
Field Type Description
FOVFIL C200 Name of .fov file

Notes
  1. It is assumed that the shape has no spectral dependence so only a single shape is used for all bands

  2. By default, the FOV is allowed to distort with refraction at low altitudes. This can be switched off by adding the FVZ flag in the *FLG section.

  3. Since only one sweep is processed at a time, there is no particular advantage in having a FOV representation which matches the retrieval grid spacing.

Example
*FOV mipas_5pt.fov ! 5 pt representation of MIPAS FOV
