				CURSOR COMMANDS

The indicated spectrum is the one with a point closest to the cursor position.

? - Print help summary
a - Append a new spectrum following the indicated spectrum
i - Insert a new spectrum before the indicated spectrum
d - Delete the indicated spectrum
e - Insert last deleted spectrum before indicated spectrum
l - Define the user label at the indicated position
p - Define the label position at the indicated position
o - Reorder the spectra to eliminate gaps
q - Quit
r - Redraw the plot
s - Repeatedly shift the indicated spectrum position with the cursor
     q - Quit shift                      x - Shift horizontally in velocity
     s - Shift vertically scale          y - Shift vertically in offset
     t - Shift horizontally in velocity  z - Shift horizontally in velocity
         and vertically in scale             and vertically in offset
u - Set a wavelength point using the cursor
v - Set a wavelength scale using the cursor
w - Window the plot
y - Automatically layout the spectra with offsets to common mean
z - Automatically layout the spectra scaled to common mean


			COLON COMMANDS

A command without a value generally shows the current value of the
parameter while with a value it sets the value of the parameter.  The
show commands print to the terminal unless a file is given.  For the
spectrum parameters the index specification, "[index]", is optional.  If
absent the nearest spectrum to the cursor when the command is given is
selected.  The index is either a number or the character *.  The latter
applies the command to all the spectra.

.nf
:show <file>		   Show spectrum parameters (file optional)
:vshow <file>		   Show verbose parameters (file optional)
:step <value>		   Set or show step
:fraction <value>	   Set or show autolayout fraction
:label <value>		   Set or show label type
				(none|imtitle|imname|index|user)

:move[index] <to_index>	   Move spectrum to new index position
:shift[index|*] <value>	   Shift spectra by adding to index
:w0[index|*] <value>	   Set or show zero point wavelength
:wpc[index|*] <value>	   Set or show wavelength per channel
:velocity[index|*] <value> Set or show radial velocity (km/s)
:redshift[index|*] <value> Set or show redshift
:offset[index|*] <value>   Set or show intensity offset
:scale[index|*] <value>	   Set or show intensity scale
:xlpos[index|*] <value>	   Set or show X label position
:ylpos[index|*] <value>	   Set or show Y label position
:ptype[index|*] <value>	   Set or show plotting type
:ulabel[index|*] <value>   Set or show user labels

:/title <value>		   Set the title of the graph
:/xlabel <value>	   Set the X label of the graph
:/ylabel <value>	   Set the Y label of the graph
:/xwindow <min max>	   Set the X graph range
				(use INDEF for autoscaling)
:/ywindow <min max>	   Set the X graph range
				(use INDEF for autoscaling)
 

Examples:
    w0		  Print value of wavelength zero point
    w0 4010	  Set wavelength zero point of spectrum nearest the cursor
    w0[3] 4010	  Set wavelength zero point of spectrum with index 3
    w0[*] 4010	  Set wavelength zero point of all spectra
