Equal mass BBHs, corotating, maximal slice

These data sets correspond to Table IV of Cook & Pfeiffer, 2004, and
were computed as follows:

1. Solve the initial value problem as described in Cook & Pfeiffer
   with excision radius 0.785798137104587, and with the centers of the
   excised spheres at locations +d/2 and -d/2 along the x-axis.
   (Therefore, 0.785... is the radius of the apparent horizon in the
   data sets).

2. Extrapolate conformal factor, shift and Lapse*psi into the excised
   regions down to an inner radius of 0.75*r_{AH}. This is the minimal radius
   for which the data sets contain data.

3. Compute lower metric, lower extrinsic curvature, lapse and shift
   from the extrapolated data.  Note that the extrapolation does not
   incorporate the constraints, and therefore the constraints are not
   necessarily satisfied interior of the apparent horizons.




The data sets are labeled by separation d.  Each archive contains:

- Several subdirectories LevX with the actual data.  The number 'X' denotes 
  the refinement factor of the data; the larger 'X', the higher the accuracy.

- A text file "Convergence," containing some information about the
  convergence of each resolution.  This is a guide to decide whether a
  coarser resolution of the initial data sets may be sufficient for a
  given application.  Again, the rows corresponds to different
  resolutions, starting with Lev0; thus, initial data supplied on Lev3 
  corresponds to the fourth row. The colums are... 
    1. N        - cube-root of number of collocation points 
    2. Nor-Linf - maximal difference of (psi, beta, Npsi) at the
                  collocation points between this resolution and 
                  the next-LOWER one.
    3. Nor-L2   - as Nor-Linf, but root-mean-square difference
    4. Ham-Linf - maximal residual of the Hamiltonian constraint 
                  at the collocation points 
    5. Ham-L2   - ditto, but root-mean-square difference 
    6. Mom-Linf - maximal residual of the momentum constraint 
                  at the collocation points 
    7. Mom-L2   - ditto, but root-mean-square difference

- A text file "AdmQuantities," containing a couple of
  characteristic numbers of the inital data set for each resolution. 
    1. N           - cube-root of the number of collocation points
    2. J_ADM[2]    - unscaled ADM angular momentum 
    3. Sph-Exp_MAH - irreducible mass (i.e. sqrt(Area/16 pi) )  
                     of each apparent horizon
    4. EADM_corr   - ADM-energy 
    5. EADM_corr   - ADM-energy minus twice the Komar-mass 
    Each row in "AdmQuantites" corresponds to one particular resolution,
    starting with Lev0;  thus, initial data supplied on Lev5 corresponds 
    to the sixth row. 

- A text file "Omega," containing the unscaled orbital angular frequency
  for this data set.  This number needs to be passed into the function
  ReadData (see PublicID.hpp).

Note: Omega is adjusted so that Komar-mass and ADM-energy are equal.
However, this adjustment has been performed on the comparatively
coarse resolution Lev2.  Therefore, ADM-energy and Komar-mass coincide
only to the truncation error of Lev2.
