IDENTIFY HELP
STATUS LINE
The status line gives the pixel position, fitted wavelength, user wavelength,
wavelength residual, and optional line identification:
pixel fitted user residual [identification]
CURSOR KEY SUMMARY
? Help l Match list (fit) w Window graph
a Affect all features m Mark feature x Crosscorrelate peaks
b Deblend n Next feature y Find peaks
c Center feature(s) o Go to line z Zoom graph
d Delete feature(s) p Pan graph + Next feature
f Fit positions q Quit - Previous feature
g Fit zero point shift r Redraw graph . Nearest feature
i Initialize s Shift feature I Interrupt
j Preceding line t Reset position
k Next line u Enter coordinate
COLON COMMAND SUMMARY
:show [file] :features [file] :coordlist [file]
:cradius [value] :threshold [value] :database [file]
:ftype [type] :fwidth [value] :image [image]
:labels [type] :match [value] :maxfeatures [value]
:minsep [value] :read [image [ap]] :write [image [ap]]

CURSOR KEYS
? Clear the screen and print menu of options
a Apply next (c)enter or (d)elete operation to (a)ll features
b Mark and de(b)lend features by Gaussian fitting
c (C)enter the feature nearest the cursor
d (D)elete the feature nearest the cursor
f (F)it a function of pixel coordinate to the user coordinates
g Fit a zero point shift to the user coordinates
h Match coordinates in the coordinate list without modifying the fit
i (I)nitialize (delete features and coordinate fit)
j Go to the preceding image line or column in a 2D or multispec image
k Go to the next image line or column in a 2D or multispec image
l Match coordinates in the coordinate (l)ist and fit/refit the dispersion
m (M)ark a new feature near the cursor and enter coordinate and label
n Move the cursor or zoom to the (n)ext feature (same as +)
o Go to the specified image line or column in a 2D or multispec image
p (P)an to user defined window after (z)ooming on a feature
q (Q)uit and continue with next image (also carriage return)
r (R)edraw the graph
s (S)hift the current feature to the position of the cursor
t Reset the position of a feature without centering
u Enter a new (u)ser coordinate and label for the current feature
v Compute a redshift and velocity from the fitted and user coordinates
w (W)indow the graph. Use '?' to window prompt for more help.
x Crosscorrelate features with the data peaks and reregister
y Automatically find "maxfeatures" strongest peaks and identify them
z (Z)oom on the feature nearest the cursor
. Move the cursor or zoom to the feature nearest the cursor
+ Move the cursor or zoom to the next feature
- Move the cursor or zoom to the previous feature
I Interrupt task and exit immediately. Database information is not saved.
COLON COMMANDS
The parameters are listed or set with the following commands which may be
abbreviated. To list the value of a parameter type the command alone.
:show file Show the values of all the parameters
:features file Write feature list to file (default is STDOUT)
:vlog file Write velocity information to file (default is STDOUT)
:coordlist file Coordinate list file
:cradius value Centering radius in pixels
:threshold value Detection threshold for feature centering
:database name Database for recording feature records
:ftype value Feature type (emission or absorption)
:fwidth value Feature width in pixels
:image imagename Set a new image or show the current image
:labels value Feature label type (none|index|pixel|coords|user|both)
:match value Coordinate list matching distance
:maxfeatures value Maximum number of features automatically found
:minsep value Minimum separation allowed between features
:read name ap Read a record from the database
(name and ap default to the current spectrum)
:write name ap Write a record to the database
(name and ap default to the current spectrum)
:add name ap Add features from the database
(name and ap default to the current spectrum)
:zwidth value Zoom width in user units
Labels:
none - No labels
index - Sequential numbers in order of increasing pixel position
pixel - Pixel coordinates
coords - User coordinates such as wavelength
user - User labels
both - Combination of coords and user
