<STRONG>Description:</STRONG>
<UL>
<LI>The <TT>histsmth</TT> and <TT>scatsmth</TT> programs smooth univariate
and bivariate distributions. The <TT>bivplt</TT> program documented here
displays the results. The plot also shows the original data pairs and the
original unsmoothed data histogram. </LI></UL>

<STRONG>Parameters:</STRONG>
<UL>
<LI><B>datafl:</B> The data file with the paired data in a simplified
Geo-EAS format.
<LI><B>icolx, icoly,</B> and <B>icolwt:</B> The columns for the <I>x</I>
variable (horizontal axis), <I>y</I> variable (vertical axis), and weight
(if less than or equal to zero then equal weighting is used; otherwise, the
weight is used to calculate the summary statistics).
<LI><B>ilogx</B> and <B>ilogy:</B> set to 1 if log scaling has been used for
the <I>x</I> or <I>y</I> axis respectively.
<LI><B>tmin</B> and <B>tmax:</B> all values strictly less than <B>tmin</B>
and strictly greater than <B>tmax</B> are ignored.
<LI><B>smoothx:</B> the data file with the smoothed <I>x</I> distribution.
<LI><B>icolvr</B> and <B>icolwt:</B> the column location for the variable
and the weight (probability).
<LI><B>smoothy:</B> the data file with the smoothed <I>y</I> distribution.
<LI><B>icolvr</B> and <B>icolwt:</B> the column location for the variable
and the weight (probability).
<LI><B>smoothxy:</B> the data file with the smoothed bivariate distribution.
<LI><B>icolx, icoly</B> and <B>icolwt:</B> the column locations for the
<I>x</I> and <I>y</I> variables and the weight (probability).
<LI><B>outfl:</B> file for PostScript output.
<LI><B>imap</B> and <B>icolor:</B> specify whether a pixel map of the
bivariate probabilities will be created (<B>imap</B>1 will create one) and
whether it will be color (<B>icolor</B>1) or gray scale (<B> icolor</B>=0).
<LI><B>pmin, pmax</B> and <B>pinc:</B> minimum and maximum plotting limits
for the pixel map.
<LI><B>title:</B> a 40-character title for the top of the plot.
