The overall directory

The directory information is as follows, with the names of the variables as in the subroutine libhdr, where this data is read from the `library' file.

libid:

This is intended to be identification for the library in a packed format, but it is not clear what the packing is, since all of our libraries have the same identifier. The reference [3] gives an explanation, but it is clearly not followed.

libdate:

The date the library was created. Thus, 930914 represents 14 September 1993.

isonum:

The number of target isotopes in the input file.

zas:

An integer array of the ZA numbers 1000*Z + A, atomic number and mass number for targets in the input file. This array is declared in the file `iodata.h', where it is called isolst. A value of A = 0 denotes the natural element, so that ZA = 28000 is natural nickel. Also, the special values ZA = 99120 and 99125 denote, respectively, short-lived and long-lived fission fragments.

levels:

The excitation levels for the targets.

abunds:

Abundances are read in but never used.

temp:

The temperatures of the targets.

tdadds:

An integer array of addresses of the individual target directories.
