Limb darkening observations are important for the construction and verification
of solar model atmospheres. We investigate the consistency of solar limb
darkening
data, published for the UV wavelength region between 2000 and 3300 Å, from
the comparison of ratios based either on direct limb darkening
observations or on absolute irradiance (F) and disk–center intensity (I0)
measurements. There exists a discrepancy between
the limb darkening data of Moe & Milone and other, direct or
indirect, limb darkening observations.
