Re: 20010509: help for gdradr



Kevin,

You should not change the mod_res.tbl file. You changed the location of the nts
restore file ($NMAP_RESTORE/radar/nexr/n0r and $NMAP_RESTORE/radar/nexr/n0r_qc)
to be data files. The restore files are the gdplot2 settings to be used for
the plot.

The rest should probably work.
