I have finally found positioning commands that give a reasonable (but
not perfect) representation of the Sun symbol, as in the following
function:

***
function sunsymbol

; Returns the Sun symbol (circle with a dot in the middle)
; as a postscript character string. This is available as a vector
font as
; the string '!9n' but it is not in the standard postscript set. Note
that
; this routine already includes subscript output positioning commands.
; EXAMPLE:
; To make the X-axis of a plot read M/M_Sun
; IDL> plot,indgen(10),xtit = 'M / M' + sunsymbol()

if (!P.FONT EQ -1) or (!D.NAME NE 'PS') then return,'!D!9n!N!X' else
begin

;Want to use /AVANTGARDE,/BOOK which is the default font 17, but to make
sure
;that ISOLATIN encoding is turned off, we'll define our own font.

device,/AVANTGARDE,/BOOK,ISOLATIN=0,FONT_INDEX = 20

return, '!20!S!DO!R!I ' + string(183b) + '!X!N'
endelse
end
***

Jack Saba pointed to me that Sun symbol is the command /odot in TeX, and
so that it
might be possible to use the OUTPUT keyword in DEVICE to output the same
string used
by TeX (after the TeX file is converted to postscript). But I think
that there is no
easy way to tell IDL to use a postscript font other than the "standard
35" available
fonts. Or is there???
