If the channel you are measuring cannot be defined in the Cross-Sectional Area File (such
as a partly filled ovoid pipe), you must supply your own Area Rating Table. This is called a
User Area Rating Table. This is only necessary if you cannot create a Cross-Sectional Area
File. For most applications, the Area Rating Table is generated automatically from a Cross-
Sectional Area File you create.
A User Area Rating Table is a text file with 1,000 entries spread evenly over the table range
(as specified in the scheme) representing the cross-sectional area for each depth. For
example, if the table range is 2m (2,000mm) then with 1,000 entries spread evenly, each
entry is 2mm apart.
This table shows the depth for which each entry in the file represents an area:

There is no special format for the file, only that each entry must be separated by whitespace
(spaces, tabs, or new lines) and that there are exactly 1,000 entries. The numbers must be
positive (zero or greater) and may include a fractional part. The area values are in mm
