This appendix contains the following files, referred to in the paper "Explicit calculations of automorphic forms for definite unitary groups":

• code-level2.zip – programs to compute the slopes of the U_p operator acting on forms of weight L, where L is the subgroup of elements of GL₃(Z_p) with first column (*, 0, 0)^T mod 2.
• readme.txt – instructions (this file is also included in the .zip file).
