1 MAP_AVER

        Average several planes of a 3-D image to produce a 2-D image.   This
    task  can be used for example on LMV data cubes to get average intensity
    images. To convert to integrated  intensities,  you  must  multiply  the
    resulting image by NC$[2]-NC$[1]+1.


2 INPUT_MAP$
        TASK\FILE "Input image" INPUT_MAP$

    The input map name. It must be a 3-D image.

2 OUTPUT_MAP$
        TASK\FILE "output image" OUTPUT_MAP$

    The output map name. This will be a 2-D image.
2 NC$
        TASK\INTEGER "First and Last channel" NC$[2]

    The first and last planes averaged to produce the result.
