Key: in
The input image containing the data cube. (No default)
The output clump assignment file (also a miriad datacube
with the same dimensions as the input) has the name in.cf
Key: dt
The contour increment (no default)
Key: start
The starting contour level (default=1)
Key: nmin
Minimum number of pixels in each clump.
Any clumps with fewer pixels are rejected (default=4).
