# Dispersion solution
# The DLD1P_A_0 and DLD1P_A_1 terms have been fitted, using observations
# of QSOs at z=0.098 (Ly a 1335 AA, C IV 1701 AA) and z=0.168 (Ly a 1420 AA)
# The reliability of the wavelength scale may decrease outside this
# range, particularly at longer wavelengths.
# The DLD1P_A_2 - DLD1P_A_5 terms are adopted from ground calibrations,
# ISR 00-01 (Bohlin et al.)

# Based on observations of LDS749B and WD1657+343
# Valid for wavelength range of approximately 1150 - 2000 AA
# The flux calibration refers to an aperture height of +/- 0.5 arcsec 
# (+/-17 pixels)
