Hi David!

Thanks for the quick reply.

This is the part of the code that does the plot:

cgplot, findgen(100),title=strtrim(string(((w[i+j]-lref)/lref)*a.c/1 d5,form='(I10)'),2),$
xsty=1, ysty=1, charsize=0.8,$
xrange=[reform(astro[0,0,0]),reform(astro[size[1]-1,size[2]- 1,0])],$
yrange=[reform(astro[0,0,1]),reform(astro[size[1]-1,size[2]- 1,1])],$
/nodata, position=p

;;; this is my iso-velocity image
cgimage, bytscl(rot(img, 0, missing=0), min=mindisplay, max=maxdisplay), position=p, /overplot,$
xrange=[reform(astro[0,0,0]),reform(astro[size[1]-1,size[2]- 1,0])],$
yrange=[reform(astro[0,0,1]),reform(astro[size[1]-1,size[2]- 1,1])]

;;; normalized intensity colorbar
cgColorBar, position=[p[2]+0.005, p[1], p[2]+0.02, p[3]],$
/vertical, /right, charsize=0.8,$
range=[mindisplay,maxdisplay]

;;; this is just to show the axis in white in my iso-image
cgplot, findgen(100),$
xsty=1, ysty=1, xtickformat='(A1)', ytickformat='(A1)', axiscolor=cgcolor('white'),$
xrange=[reform(astro[0,0,0]),reform(astro[size[1]-1,size[2]- 1,0])],$
yrange=[reform(astro[0,0,1]),reform(astro[size[1]-1,size[2]- 1,1])],$
/nodata, /noerase, position=p, charsize=0.8

;;; this is the contour obtained from a FITS image
;;; with astrometric solution stored in header.
;;; The size and orientation are not the same as
;;; that of my iso-velocity image.
cgcontour, rot(data_img, 0.), levels=[0.9,5,8],$
color='white', background='black',$
label=0, olevels=olevels, /onimage, /missing

The result for one image can be seen in this link:
