Manuscript Title: A program suite for the calculation of ro-vibrational spectra of triatomic molecules.
Authors: J. Tennyson, S. Miller
Program title: SELECT
Catalogue identifier: ABJX_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 55(1989)149
Programming language: Fortran.
Computer: CRAY-1.
Operating system: COS.
Peripherals: disc.
Keywords: Molecular physics, Vibration, Basis set selection, First-order Perturbation theory.
Classification: 16.3.

Nature of problem:
SELECT selects basis sets for TRIATOM.

Solution method:
A basis is selected either according to its quantum numbers and/or the value of its diagonal matrix element.

Restrictions:
The size of matrix that can be handled by TRIATOM.

Unusual features:
A user supplied subroutine containing the potential energy as an analytic function (optionally a Legendre polynomial expansion) may be needed. SELECT produces a file which drives TRIATOM.

Running time:
Negligible compared to TRIATOM.
