c param_defs.inc -- integer constants for decoded_exact_model
c $Header$

c
c For reasons explained in our param.ccl file, we decode the  exact_model
c parameter, and all our other string-valued parameters used in computing
c the stress-energy tensor, into integers.  This file contains #define
c definitions for those integers.
c

c
c For each parameter, the value 0 is deliberately *not* a legal value
c for the decoded integer, to help catch bugs where the decoded integer
c is not initialized properly.

c ***** definitions for decoded_exact_model *****
c
c These *MUST* be distinct integers, and there must be precisely one
c definition for each value of  exact_model  in  param.ccl .  It is not
c necessary that they be in numerical order, that is just to make things
c look prettier.
c
c N.b. We are counting on the preprocessor being case-sensitive here,
c      since these same names with EXACT changed to Exact, are names
c      of subroutines for the individual metric types!
