PRO JAN20overlay, PS=ps, TIMES=times, BEAM=beam
;
; Prepares an overlay plot of TRACE, 250-500 keV contours and 2.2 MeV circles.
;
; 13-May-05		Initial version, adapted from NOV02overlay.pro
; 17-May-05	gh	Incorporated TRACE pointing corrections
; 28-Nov-05 gh	Updated to reflect November 26 mapping results.
;
; beam = FWHM beam diameter to be overlaid
;
; See Sam Krucker's emails of 3 Dec 2003 and 25 May 2004.
