1 CIRCLE Compute the radial profile of each planes of an input cube
CIRCLE
This program computes annular averages on an input cube to produce an
output map. Each line of the output map is the radial profile for one
particular plane of the input cube. The task can be used to derive the
radial profiles, for example in circumstellar envelopes. The radial
pixel separation is always the X and Y increment. If the X and Y
increments are different, the averages are therefore computed on
elliptical rings, despite the name of the task.
2 Y_NAME$
TASK\FILE "Input cube" Y_NAME$
The name of the input cube on which the circular averages are computed.
2 X_NAME$
TASK\FILE "Output image" X_NAME$
The name of the output image in which the circular averages are stored.
2 CENTER$
TASK\REAL "Coordinates of centre" CENTER$[2]
The X and Y user coordinates of the circle center.
2 PROFILE$
TASK\INTEGER "Number of radii" PROFILE$
The number of rings for which an average value is computed. The
distance between successive rings is fixed by the X and Y increments.
