This package contains a climatological model of the equatorial
electric field (EEF). It is a model of five parameters: longitude,
local time, season, solar flux, and lunar local time. Included in the
package are the coefficents for the mean model and standard deviation
model, along with source code required to plot one dimensional slices of
the model for any desired parameter.

To compile source code under Unix:
==================================

The GNU Scientific Library (v1.9) is required for compiling this source
code. See http://www.gnu.org/software/gsl/

Once GSL is installed, simply typing 'make' will compile
all files and create the executable "eefm_plot". This program
can be used to generate 1D plots of the EEJ model for any
choice of parameters with any of the four parameters as the plotting
variable.

Execute eefm_plot -h to find out all the command line options for
how to specify parameter values.

Notes regarding using the source routines in your own work
==========================================================

The important source code files you'd need to include in your
own work are:

eefm_calc.c   - contains routines for computing the EEJ mean and
                standard deviation

eefm_basis.c  - contains the basis functions for each parameter
                in the model

eefm_plot.c   - this is an independent driver program which will
                demonstrate how to call the routines in eefm_calc.c

other         - the other source files contain various computational
                routines needed by the model
