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

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
