A brief description of the Programs

Programs a written in FORTRAN'77 with minimum isolated system dependency. All programs are interactive, command oriented, with online help, adopting a front-end structure similar to John Tonry's plot package MONGO. Many additional VAX/VMS-like commands, Real and logical arguments that could be FORTRAN statements or predefined variables which are interpreted.

IASG Galaxy Model Software interface between theoretical models of the Galaxy distribution function (density and Kinematics), and the directly observed quantities (star-counts, proper motion, line-of-sight velocity)

DEMON plot package A much DEveloped MONgo-like plot program. Many additional commands for manipulation, analysis and display of tabular data. TeX-like format for labels. Practically compatible with MONGO'87
KALC interpretive FORTRAN calculator Demonstration calculator program for interpretive FORTRAN arithmetic and logical expression evaluator, with variable names.
IACTEST Vertical cut and paste editor Demonstration program for interactive front-end used in IASG and DEMON
ASTRO program for Astronomical transformations. Interactive program to do simple astronomical transformations. Still only a demonstration program.
