FIELD_STAT

        FIELD_STAT

    This  task  computes  the integrated spectrum of a number of fields in a
    data cube. It requests as input a 3-D cube, and a label  image  (usually
    produced by task FIELD_FIND).  The output is a table where:
    - first column is the channel per channel velocity,
    - next even columns contain the number of data points in the correspond-
      ing field, repeated for each channel (not an optimal storage indeed!),
    - next odd columns are the average spectrum for each field.
