Hi David,
the code (without missingvalue):
TRIANGULATE, theta0i, thetaobsi, tr, b
mx=TRIGRID(theta0i, thetaobsi, ydi, tr, nx=res, ny=res, $
xgrid=xo, ygrid=yo, max_value=25)
levels=50
step = (Max(mx) - Min(mx)) / levels
userLevels = IndGen(levels) * step + Min(mx)
cgcontour, mx, xo, yo, /fill, xstyle=3, ystyle=3, $
levels=userLevels, xrange=[0.07,0.44], yrange=[0.04,0.45], $
xtitle="Jet half opening angle [rad]", $
ytitle="Observer half angle [rad]", $
Position=[0.1, 0.1, 0.83, 0.95], $
charthick=2, charsize=1.5, thick=3
cgColorbar, range=[12, 25], title="AB magnitude", $
/reverse, /vertical, /fit, $
divisions=7, charthick=2, charsize=1.5
