Folks,
I'm asked about every 10 minutes around here how to
get a good looking sun symbol on IDL plots. A sun
symbol is a circle with a dot in the center of it.
Usually you subscript a capital M with it, and it
represents the mass of the sun, a standard astronomical
unit.
I've read the back issues of the IDL newsgroup (which are
bound in leather on my shelves), and I've seen Wayne Landsman's
sunsymbol.pro in the Astro Library (how in the world
does anyone do any astronomy without Wayne's Library!?),
but I thought I would ask if there is any news I may
have overlooked.
Or, how is the world does LaTeX do it? They seem
to get it right, but we can't seem to work it out as
nicely.
Cheers,
David

OK, thanks Mike. I am still on v7.1 though...

Here is what I do with reasonably good results (i.e., not an off-
center dot). I adapted Michael Galloy's vis_psfrag for this. The basic
steps are:
1. Generate your plot in PS with the /TIMES switch and !P.FONT=0
2. Run ms_psfrag with this syntax:
ms_psfrag,input_ps_filename,latex_template_filename,output_p s_filename, "actual
text in the ps","replacement latex text"
You will have to download ms_psfrag.pro (here:
http://astro.phy.vanderbilt.edu/~sinham/code/ms_psfrag.pro). Also, you
have to create a Latex template file -- the contents for the latex
template are in the comments on the top of ms_psfrag.pro.
I still haven't figured out how to sent the font size correctly so you
will have to play around with this line in the latex template:
\psfrag{tag_text}[c][c][1.5]{replacement_text} ,
where 1.5 represents the font size scaling. You will have to change
that 1.5 value such that the replacement font size is similar to other
font sizes in the plot.
For the solar mass symbol, the latex replacement text would be '$M_
\odot$'. A code snippet could be:
-----------------------
set_plot,'ps'
!p.font=0
fname = 'plot.eps'
templatefname = 'figure.tex' ;;;; you will have to create this latex
template file as figure.tex
device,filename=fname,/color,/portrait,bits_per_pixel=8,/enc apsulated,/
times
xtitle = 'ZM'
plot,findgen(10),xtitle=xtitle
device,/close
outfname = fname
ms_psfrag,fname,templatefname,outfname,xtitle,'Mass [M$_\odot$]'
-----------------------
Hope this helps.
Cheers,
Manodeep

Hi,
Actually, sunsymbol.pro has off-center sun symbol as you say, and
vis_psfrag.pro is not very easy to handle (especially because it
replaces the full string by the sun symbol as far as I understand...).
So, no sun symbol solution yet for postscript fonts in IDL7.1...
Thanks though.
