Any input record that is not recognized as command is considered to be a data record. In a data record, all character data must be specified in single quotes, e. g. 'Character Data', so that it can be read using unformatted FORTRAN reads. Any unquoted entry is taken to be the begining of a new command or data record. In the case of a data record, the unquoted character string is the label for the data record. The pound symbol '#' is the begining of a comment and all characters after the '#' symbol are ignored.
This data record contains the information needed to construct the asymptotic part of the V_{CP} potential.

This record specifies which orbitals to use from the Quantum
Chemistry program, the form is specific to the program being used.
In G03Cnv and MoldenCnv there is a single read of the form
nmos
, nmoe
or
-nmor
, (nmos(i), nmoe(i), i = 1, nmor)
nmos
is the start of a series of orbitals to use and nmoe
is the
corresponding end of a sequence. if the first number is negative
then a series of such numbers are read in. This option can also be used
to reorder the orbitals. This reordering is sometime required when a set of degenerate core orbitals
are ordered such that groups of orbitals that are degnerate by symmetry (e. g. pi-x and pi-y orbitals)
are not contiguous as is required in the RotOrb.
This is an optional data record.
If this record is present then when the

for each partial wave, with partial waves with the same value of l being summed together.
