PROJECT 2:

i) First part

- code the Feautrier solver for a true formal solution
  (source function fully known)
- code one of the 1-st order schemes (short characteristics
  or DFE)
- formalism is described in detail in Chap 12. 
  (to be found at http://aegis.as.arizona.edu/~hubeny/SA3)
- take a test case, for instance that presented at the end
  of Sect. 12.4, with a simple source function that allows
  for an analytical solution (eq. 12.170), and test the accuracy 
  of the method on the number of depths (as done in 12.4),
  and also on the angle mu.

ii) Second part.

- code the Feautrier scheme for a solution of the
coherent scattering problem, with the Variable
Eddington Factors scheme - described in Chap. 12.
(section 12.5). For detailed explicit expressions of
teh matrix elements, refer to the attached document
(vef.pdf).


The papers are due, and the short 10 minute presentations
of the group representatives will be held, 
on Tuesday, Nov 3.
