When I use the \sun symbol in cgplot titles with output to a pdf file, it comes out with the dot not centered in the ring. Is there something I can do about that? I usually use it as a subscript but just the symbol by itself also has this problem.
Here is an example:
IDL> cgplot, [0, 1], [0, 1], xtitle = '$\sun$', output = 'test.pdf'
This is my output:
http://www.isf.astro.su.se/~mats/test.pdf
Is there something I can do about that? I currently don't set the ps_font to anything, would this maybe work better with a font other than the default?

Try this:
IDL> cgset_ttfont, 'dejavusans'
IDL> cgplot, [0, 1], [0, 1], xtitle = '$\sun$', output = 'test.pdf'
Cheers,
David

Thanks Dave.
That made the sun symbol look right, but now it doesn't respond to subscripting:
IDL> cgset_ttfont, 'dejavusans'
IDL> cgplot, [0, 1], [0, 1], xtitle = 'R$\sub$$\sun$', output = 'test.pdf'
The new version of test.pdf is now at the same url as before: http://www.isf.astro.su.se/~mats/test.pdf

This needs to be explained better in the documentation, but construct
your string like this:
cgset_ttfont, 'dejavusans'
cgplot, [0, 1], [0, 1], xtitle = 'R$\sub\\sun$', output = 'test.pdf'
Cheers,
David

Wow! This fixes an issue that has persisted 20 years in direct graphics. For those of us still stuck on then even more ancient PODG (plain-ole-direct-graphics), you can invoke the DejaVuSans font using the formatting code !10. E.g.:
xyouts,.5,.5,/normal,'M!D!10!Z(2299)!X!N',CHARSIZE=2,FONT=1
I see now that sunsymbol.pro has updated, using the more astronomically correct symbol at !Z(2609). Either works (pick your favorite).
