18.35 UV_RESAMPLE

[CLEAN\]UV_RESAMPLE [Nc Ref Val Inc] [/FILE FileIn FileOut] [/LIKE Mold]

With no option, resample the UV data loaded by READ UV on a different velocity scale. All other UV commands except UV_COMPRESS work on the "Resampled" UV table. The output spectral sampling is defined by

      Nc   new number of channels
      Ref  New reference pixel
      Val  New velocity at reference pixel
      Inc  Velocity increment

Any argument can be set to * for an automatic determination based on the values of the other arguments. The automatic determination of NC preserves the velocity coverage.

The "Resampled" UV table is a simple copy of the original one after a READ UV command, or after a UV_RESAMPLE or UV_COMPRESS command without arguments.

With the /FILE option, the internal buffers are not used: the UV data is read from file FileIn and the resampled output is written in file FileOut. In this case, the /LIKE option can be used to define the spectral sampling as identical to the Mold file.
