Evolution of stars (interpolating grid of stellar models).

The HR1 program presents an evolution of stars by interpolating grid of stellar models, computed at Geneva Observatory by Schaller et al. (1992). It can run in an interactive mode, for example in the Xwindow environment, or in batch mode, producing separate images in various formats (e.g., GIF, PostScript).

The code is written in FORTRAN77, using PGPLOT library for graphics I/O. Look at screenshots.

Before executing the hr1 program, you have to set up PATH and PGPLOT_DIR environment variables to the directory, where pgplot_server and grfont.dat are situated.

The second possibility is to build your own binaries suitable for your operating system. Download the source file hr1.src.tar.gz, install the PGPLOT library, don't forget set up PGPLOT_DIR properly, choose tables by editing file hrpack.in, edit Makefile, and run make.
