Query: Solar limb darkening function and solar diameter with eclipses
  observations   We introduce a new method to perform high resolution astrometry of the solar
diameter from the ground, through the observations of eclipses. A discussion of
the solar diameter and its variations is linked to the Limb Darkening Function
(LDF) using the luminosity evolution of a Baily's Bead and the profile of the
lunar limb available from satellite data. The inflexion point of the LDF is
defined as the solar limb. The method proposed is applied for the videos of the
eclipse in January, 15, 2010 recorded by Richard Nugent in Uganda and Andreas
Tegtmeier in India. An upper limit for the inflexion point position has been
set for that eclipse.
