PLOT/DISTORTION wave [delta] [mode]
16
Plot the fitted position of arc lines in wavelength/y-coordinate space.
19
The fitted positions of the line catalog are plotted in
20
wavelength/y-coordinate space. The commands allows to check
21
the regularity of the fitted dispersion relation along the
22
y-axis. Both row-by-row and bivariate solutions can be
23
verified depending on the mode.
26
PLOT/DISTORTION wave [delta] [mode]
28
wave = Arc line wavelength. The wavelength must be chosen
29
from the line catalog (session keyword LINCAT).
31
delta = Half-range in pixels of the wavelength space.
32
Default value is 0.5, which means that the full
33
graphic window represents one pixel on the spectrum.
35
mode = Dispersion relation mode. Possible values: RBR, 2D
36
Allows to plot the row-by-row (RBR) or the bivariate (2D)
37
solution. Default is RBR.
40
CALIBRATE/LONG, PLOT/DELTA, PLOT/RESIDUAL, PLOT/CALIBRATE
43
mode = 2D can only be used if the session keyword TWODOPT
44
is set to YES (i.e. if a bivariate dispersion solution has
