Midas...> <TT>PLOT/CALIBRATE</TT> <BR>
<BR>
plots the central row of the comparison spectrum and adds
the line identifications obtained. This plot can be used for coarse
consistency checks. A hardcopy may be handy for future, similar work.
<BR> <BR>
Midas...> <TT>PLOT/RESIDUAL</TT> <BR>
<P>
displays the residuals (column :RESIDUAL in table <B>line.tbl</B>) as
a function of wavelength. This command is used to judge the quality of
the calibration.
<BR> <BR>
Midas...> <TT>PLOT/DELTA</TT> <BR>
<P>
plots the dispersion relation and the residual value as
a function of the wavelength. Note that <TT>PLOT/RESIDUAL</TT>
and <TT>PLOT/DELTA</TT> display the rms
of the residuals. It is also possible to display, for all rows,
the residuals for a given line of wavelength ``wavelength'' with:
<BR> <BR>
Midas...> <TT>PLOT/DISTORTION</TT> ``wavelength'' <BR>
<P>
The wavelength value must correspond to a value from the catalog
<!-- MATH: $\fbox{LINCAT}$ -->

The residuals are plotted in the graphic window
with a scale such that the full extent of the graph corresponds
to one pixel of the spectrum.
