+
+				CURSOR COMMANDS
+
+All plots may not be available depending on the number of focus values and
+the number of stars.
+
+?	Page this help information
+a	Spatial plot at a single focus
+b	Spatial plot of best focus values
+d	Delete star nearest to cursor
+e	Enclosed flux for all stars at one focus and all focus for one star
+f	Size and ellipticity vs focus for all data
+i	Information about point nearest the cursor
+m	Size and ellipticity vs relative magnitude at one focus
+n	Normalize enclosed flux at x cursor position
+o	Offset enclosed flux to x,y cursor position by adjusting background
+p	Radial profiles for all stars at one focus and all focus for one star
+          The profiles are determined from the derivatives of the enclosed flux
+q	Quit
+r	Redraw
+s	Toggle magnitude symbols in spatial plots
+t	Size and ellipticity vs radius from field center at one focus
+u	Undelete all deleted points
+x	Delete nearest point, star, or focus (selected by query)
+z	Zoom to a single measurement showing enclosed flux and radial profile
+<space> Step through different focus or stars in current plot type
+
+
+			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.
+
+:level <val>	Level at which the size parameter is evaluated
+:overplot <y|n> Overplot the profiles from the narrowest profile?
+:radius <val>   Change profile radius(*)
+:show <file>	Page all information for the current set of objects
+:size <type>	Size type (Radius|FWHM|GFWHM|MFWHM) (**)
+:scale <val>	Pixel scale for size values
+:xcenter <val>	X field center for radius from field center plots
+:ycenter <val>	Y field center for radius from field center plots
+
+(*) The profile radius may not exceed the initial value set by the task
+    parameter.
+
+(**)
+Radius = radius enclosing the fraction of the flux specified by "level"
+FWHM   = Full-width at half-maximum based on the radially smoothed profile
+GFWHM  = Full-width at half-maximum of Gaussian function fit to enclosed flux
+MFWHM  = Full-width at half-maximum of Moffat function fit to enclosed flux
