EXPTIME =                   1.	Most analysis software needs this
DISPAXIS=                    1	Dispersion along the only axis
DC-FLAG =                    0	Linear in wavelength
CRPIX1  =                   1.	First pixel is reference
CRVAL1  =                3000.	Wavelength at CRPIX1 in Angstroms
				From parameter st_lambda.
CDELT1  =                 0.25	Wavelength per pixel in Angstroms
				From parameter pix_lambda.
W0      =                3000.	Wavelength at first pixel in Angstroms
				From parameter st_lambda.
WPC     =                 0.25	Wavelength per pixel in Angstroms
				From parameter pix_lambda.
NP1     =                    1	First pixel number
NP2     =                20001	Last pixel number
				1 + ((end_lambda - st_lambda) /
					(pix_lambda))
VELOCITY=                   0.	Redshift velocity in km/sec
				From parameter temp_vel.
BCV     =                   0.	Barycentric velocity correction
