The cells file contains design info

The cells file contains design information for
each cell in a system, including site number, system
number, cell number, hydrologic type (surface
flow—SF, or subsurface flow—SFF), plant
species names for resident vegetation, and cell
length and width. Cells are wetland areas that are
clearly delineated from other treatment areas by
dikes or uplands and that have recognizable inlet
and outlet points. There are 33 fields and 364
characters in the cells database file.
The operate file is the largest of the six linked
database files, both in terms of number of records
and character widths. It contains all operational
data for specific cells within a specific system for
a specific time period. Efforts were made to
provide average data on a seasonal basis, though
data for monthly, annual, or other time periods
also were included. Data for 5-day biochemical
oxygen demand (BOD5), total suspended solids
(TSS), total Kjeldahl nitrogen (TKN), NH4-N,
NO3-N, total nitrogen (TN), organic nitrogen,
total phosphorus (TP), dissolved phosphorus, dissolved
oxygen (DO), fecal coliforms, conductivity,
total dissolved solids (TDS), volatile suspended
solids (VSS), chemical oxygen demand (COD)
and water temperature are included in this file.
There are 110 fields and 904 characters in the
operate file.
The literat file contains selected references to
literature documents for systems included in the
six database files. Up to three individual authors
can be entered, allowing for their selective retrieval.
There are 14 fields and 508 characters in
the literat file
