The procedure sunsymbol.pro  in  http://idlastro.gsfc.nasa.gov/ftp/pro/plot/sunsymbol.pro
creates a postscript subscript Sun symbol.    (Try saying "postscript subscript Sun
symbol " 10 times fast ;-) )   However, it is something of a kluge (it draws a circle and
then a dot) and the quality may depend on your particular character thickness and size
settings.

P.S. To answer an earlier question, the procedure ploterror.pro in the same directory can
be used to plot X error bars only, by setting the Y errors to zero, e.g.

iDL> ploterror, x, y, xerr,  y*0
