Basic Information on ellplt
Task: ellplt
Purpose: Plot points in elliptical annuli.
Categories: image analysis
ELLPLT plots the values of a Miriad image along ellipses.
Key: in
Input image name. No default.
Key: region
Region of image to be displayed. See the help on region for more
information.
Key: center
The offset of the center of the annuli in arcsec (or natural units
if options=natural is used) offset from the reference pixel.
Key: pa
Position angle of ellipse major axis in degrees. Default is 0 (north).
Key: incline
The ellipse is assumed to be a circular structure that appears
ellitpical because it is viewed at some inclination. The "incline"
parameter gives this inclination angle in degrees. Default=0. (face on)
Key: radius
This gives one or two values, determining the radii of the major
axis of the annulus of interest. If one value is given, then this
is taken as the radius at the center of the annulus, and the annulus
is 5% wide. If two values are given, these are taken as the inner
and outer radii of the annulus. The units are (by default) arcsec,
but can be natural units if options=natural is used. No default.
Key: range
Min and max greyscale values for the greyscale plot. The default is
the image minimum and maximum.
Key: device
Plotting device. See the help on device for more information.
The default is not to make a plot.
Key: log
Output log file. The default is not to make a log file.
Key: options
Task enrichment options. Minimum match is active.
natural Assume keywords "center" and "radius" are in natural
units rather than arcsec.
