.SH NAME

.Pp
\fBavg_con2\fP - Average data from different contour files

.SH SYNOPSIS

.Pp
[\fIdata\fP, \fIgrid\fP] = \fBavg_con2\fP(\fIfiles\fP, \fIx\fP, \fIy\fP, \fIout\fP, \fImethod\fP
)

.SH DESCRIPTION

.Pp
This is a user interface to function \fBavg_ascii2\fP(3m) for averaging
data from
contour files.
