DESCRIPTION

CLPLOT is an interactive task to analyse spectra, position-velocity slices, and integrated velocity maps from Miriad Images. There are three basic display options:

 - Velocity-averaged x-y images over selected velocity intervals.
        Also makes velocity and velocity dispersion images.
 - Spectra at selected x-y positions. The data can be convolved
        in the x-y or velocity. Gaussian fitting routine.
 - Position-velocity maps along user selected position angles,
        or plots of intensity versus position for selected velocity
        channels. The data can be convolved in the x-y plane.

(x,y) positions are (HA,DEC) in arcsec relative to map center. Position angles are measured from the north towards the east.

The output from each option can be plotted, printed, or written out as Miriad images of velocity-averaged maps, position-velocity maps, or ascii spectra respectively. Gaussian fits are written into the log.

The task saves user-defined lists of velocity-averaged maps, position- velocity cuts, and spectra positions. These lists can be created and edited within the task, and can be passed between the three options. For example, a list of spectra or position-velocity cuts can be created with the cursor whilst displaying a velocity-averaged map. These lists are used to display the spectra and position-velocity cuts, and can be written out and read in as ascii files.

A menu option provides a choice of display style, contour levels, and units. Further interactive help is available within the task.  

PARAMETERS

in
Input image name. No default.
device
The PGPLOT plotting device.
region
Region of image to be plotted. E.g.
  % image region=relpix,box(-30,-30,20,90)(16,57)
reads in 50 x 120 pixels of image planes 16 to 57. The default is the whole Image. The current size limit is 256 in any dimension. (see parameter maxdim in clplot.h)
log
