wl1 = start of wavelength interval
wl2 = end of wavelength interval

ref: Tobiska, W.K., Revised Solar Extreme Ultraviolet Flux Model,
     JATP, in press, 1991. Also given as poster paper I.2-P1 at the
     XXVIII COSPAR, The Hague, 1990. Preprints available from author

The following intervals and lines have been slightly revised due to
reprocessing of the LASP 1989 data and incorporation of the smaller,
"nonstandard" lines into the wavelength range flux (Sep 4 1991):
     356-400(2), 401-437(2), 453-499(2), 500-550(1,2), 701-750(1),
     750-800(1,2), 801-850(1), 901-950(1), 977(1), 951-1000(1),
     1026(1), 1001-1050(1)
Far UV lines and intervals were added solely based on the SME data.
