Level 2 Help for USTATS

 Input bands for stats.  The input can either be 10 seperate files each
containing one band or one file in MSS format containing 12 bands.
The parameter MSS must be used if an MSS format file is being used.
(default is seperate files)

 Ouput data set.

 Standard VICAR size field.

 Denotes that every Nth sample & Nth line is to be used to form the
initial clusters. (Default = 20)

 Denotes that every Nth line is to be used to form the inital clusters.
(Default = 20)

 Denotes that every Nth sample is to be used to form the inital clusters.
(Default = 20)

 Specifies that the boundries of the initial clusters are spheres of
radius X. (Default = 5.0)

 Denotes that a maximum of N clusters will be formed when sampling the
input picture. (Default = 500)

 Denotes that pixels of DN I,J,... (maximum of 10 values may be given)
are to be excluded from all sampling. (Default is no DN to be excluded.)

 Specifies that the nearest neighbors of a sampled pixel are not to be
checked for inclusion into that pixel's cluster.  This will be further
explained in the Operations Section. (Default is that neighboring pixels
will be checked)

 Specifies that only the N most populous clusters will be retained as
classes for output. (Default = 10)

 Specifies that only those clusters that contain at least X percent of all
pixels sampled will be retained as classes for output. (Default is no
percentage restrictions on output classes)

Suppresses the printing of the populations and means of all clusters
formed. (Default is to print this information.)
!.VARIABLE MSS
! Denotes that the input is in MSS format and contains N spectral bands.
!(Default is one spectral band per input file)
!.VARIABLE USE
! Denotes that only bands i,j,k,... of an MSS formatted data set are to be
!used as input. (Default is all bands are used)

 Displays messages relating to the current progress of the program.
(Default is not to display progress.)

 Skips the code which combines and eliminates clusters. (Default is to
perform these steps.)
