QUANTIZE
Type:  Adverb (Scalar)
Use:   Specifies the quantization level to be used.  A quantized
       collection of numbers is more compressible and will have only
       marginally greater noise if the quantization level is well
       chosen.  Larger quantization levels will produce better
       compression but can destroy real information if they are too
       high.  QUANTIZE < 1/4 sigma causes only 1-2  percent increase in noise.

Null value:  0 => no quantization.

Tasks:
   FITAB....Writes data in FITS format to tape and disk.  QUANTIZE is
            used to quantize images before writing them in integer or
            floating formats.
