CGDISP contours

Post by bnorfolk »

Hi again,

I'm having trouble understanding how the contours in cgdisp work, so my current entry is

cgdisp
in=imagefile,imagefile
type=p,c
slev=a,1.10991E-05
cols1=1
levs1=2,3,4
device=/xs
labtyp=arcsec
beamtyp=b,l,4,45,1,3
options=wedge,blacklab,mirror
region='arcsec,box(-5,-5,5,5)'
csize=1.75
range=-2.149511E-05,2.419270E-05,lin,2

Which produces the image (attached)

Now I'm not sure why no contours are present? From my understanding since I have a slev value of 1.10991E-05, for which twice that is 2.21982E-05, and the max is 2.419270E-05, I should at least get one contour circle on my image right?

Cheers,
Brodie

Apologies I somehow had incorrectly inputted the levs1 desired contours, this issue is now solved
