| 3 | C----------------------------------------------------------------------- |
| 4 | C This subroutine calculates the neutralino (zi) subset of |
| 5 | C SSWZBF, which was too long. |
| 6 | C Valid for all scalar masses (functions in double precision) |
| 7 | C Includes Higgs sector radiative corrections (Aug. 31) |
| 8 | C |
| 9 | C Auxiliary functions are called SSWxyi, SSZxyi, where normally |
| 10 | C x indicates the SUSY particle, y the SM particle(s), and i is |
| 11 | C a counter. |
