This example uses an error array to determine the errors in the radial profile.
task: imcnts
input files: vigsnr.imh;vigsnr_err.imh;xdata$snr_exp.pl
output file: vigsnr_cnt.tab
xs> imcnts err=vigsnr_err expo=xdata$snr_exp.pl expthr=95.0 bkgdex=xdata$snr_exp
bkgdth=95.0 bkgderr=vigsnr_err
# Run the imcnts task with the appropriate parameters
source image file: vigsnr # vigsnr.imh
source region descriptor: a 300 300 0 50 n=5
# 5 annuli centered at 300,300, 0 and 50 pixels min/max radius
background image file or cts/pixel: <cr> # From the same file vigsnr.imh
bkgd region descriptor: a 250 256 100 150 # Annulus at 250,256
# 100-150 pixel width
root name for output file [root_cnt.tab]: vigsnr # vigsnr_cnt.tab

The command line for imcnts is rather long, but most of these are hidden parameters and need to be explicitly given. A more convenient way to do this is to edit the imcnts parameter files, and change all the appropriate parameters. However, these will be permanently changed (until the next re-editing) for subsequent use of this task. To do so:
xs> eparam imcnts # Edit with your favorite editor xs> imcnts # (Set in loginuser.cl)
The task will prompt for all auto parameters as above.
