CURSOR COMMANDS
All plots may not be available depending on the number of stars.
? Page this help information
a Spatial plot
d Delete star nearest to cursor
e Enclosed flux for all stars
i Information about star nearest the cursor
m Size and ellipticity vs relative magnitude
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
Profiles are determined from the derivatives of the enclosed flux
q Quit
r Redraw
s Toggle magnitude symbols in spatial plot
t Size and ellipticity vs radius from field center
u Undelete all deleted points
x Delete nearest point or star (selected by query)
z Zoom to a single measurement showing enclosed flux and radial profile
<space> Step through different stars in some plots
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
