Abstract: Especially designed for a timesharing environment, SPPLT prepares accurate Contour plots of hybrid atomic orbitals with specified contour levels, effective nuclear charge, amounts of 2s and 2p character, and geometric operations (scaling, translation, rotation). After plotting, the user can replot the same orbital with different scaling parameters, or perform calculations for a different orbital shape. The program's operational modules are contained in two source program segrnents with automatic chaining. The plotting subroutines support the Tektronix 4010 graphics terminal, the TSP-12 or TSP-212 plotting systems, and the Hewlett-Packard 7200A/7202A graphic plotters.

Note: DECUS NO. 10-212A&B is an equivalent program written in PDP-10 BASIC, Version 17.
