Description

Gathers several statistics on the "fringe" of a channel file. These statistics are then output to a pvl file that can be viewed to see if several channel files, based upon those statistics, are suitable for stitching together. The number of lines that are gathered is a function of the binning mode of the channel file being input as follows: 
  binning mode 1          48 rightmost and 48 leftmost samples gathered
  binning mode 2          24 rightmost and 24 leftmost samples gathered
  binning mode 3          16 rightmost and 16 leftmost samples gathered
  binning mode 4          12 rightmost and 12 leftmost samples gathered
  binning mode 8           6 rightmost and  6 leftmost samples gathered
The following statistics are gathered: 
  Valid Pixels
  Standard Deviation
  Average
  Minimum
  Maximum

Description

This pvl file will contain two groups. The first group will be statistics for the leftmost samples, and the second group will be statistics for the rightmost samples.

Type filename
File Mode output
Filter *.pvl

sections: SECTIONS

Description

This is the number of sub-areas that are extracted from each side of the cube. They will be spaced in such a way that there will be a section starting at the 

l/n
th line where 
l
is the total number of lines in the cube and 
n
is the number of sections specified.

Type integer
Default 5

sections: LINESIZE

Description

This is the number of lines in each section. If the user does not enter anything, or specifies an invalid number of lines (i.e. more lines than exist in the cube), the sections will be stretched to cover as many lines of the cube as possible

Type integer
Internal Default complete coverage
