IASG: A set of FORTRAN programs for Galactic Structure Analysis
Kavan U Ratnatunga
Collaborators Stefano Casertano
These programs were developed at
Institute for Advanced Study, Princeton, USA : Jan'84 - Jun'86
Dominion Astrophysical Observatory, Victoria, CANADA : Sep'86 - Dec'89
NASA Goddard Space Flight Center, Greenbelt, USA : Jan'90 - Jan'91
Mount Stromlo Observatory, Canberra, AUSTRALIA : Dec'91 - Jan'92

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.
