Purpose:    
 
19
            Plots a row of the arc spectrum and invokes command 
 
20
            GET/GCURSOR for intercative identification of lines.

            IDENT/LONG [wlc] [ystart] [lintab] [tol]
 
24
\ys\pa
 
25
            wlc    = Wavelength calibration frame
 
26
                     Session keyword : WLC; no default value
 
27
\ap\pa
 
28
            ystart = Starting row number (pixels) for identification
 
29
                     and calibration.
 
30
                     Session keyword : YSTART; default : 0

32
            lintab = Line table, as generated by command SEARCH/LONG
 
33
                     Session keyword : LINTAB; default : line.tbl
 
34
\ap\pa
 
35
            tol    = Tolerance for the identification of lines, in
 
36
                     world coordinates. This parameter must be set
 
37
                     if the interactive pointing generates too often
 
38
                     the error message: "Feature not found, try again..."
 
39
                     (No session keywords controls this parameter)

                     Default: 4.

Note:       1) This command requires two preliminary actions:\\
 
47
               - Creation of a line table with SEARCH/LONG\\
 
48
               - Creation of a graphic window with GRAPH/LONG
 
49
 
 
50
            2) If YSTART=0, its value is automatically set to the 
 
51
               central row number.
 
52
 
 
53
            3) The arc spectrum is plotted with respect to the current
 
54
               set-up of plotting parameters. To adjust the plotting,
 
55
               use commands CUTS or SET/GRAPH.
 
56
 
 
57
            4) Interactive identification of lines can be avoided by
 
58
               the command ESTIMATE/DISPERSION. This command is however
 
59
               provided on an experimental basis.
