Figaro has three directories which are used to keep various data files, such as flux calibration tables and arc line lists. The locations of these directories are not fixed, but rather they are referred to by environment variables. These environment variables are:
| environment variable | meaning |
| FIGARO_PROG_S | default or standard |
| FIGARO_PROG_L | local |
| FIGARO_PROG_U | user |
FIGARO_PROG_S is a standard directory which is always available and contains the same files in all Figaro installations. On standard Starlink systems it corresponds to directory:
/star/etc/figaro
FIGARO_PROG_L contains files local to your site and FIGARO_PROG_U your own personal files. They may or not defined at your site. You could define your own Figaro directory by adding a line similar to the following to your `.login' script:
setenv FIGARO_PROG_U $HOME/myfigarodata
By default Figaro applications will search for data files in these directories in the following order: first your default directory, then FIGARO_PROG_U, then FIGARO_PROG_L and finally FIGARO_PROG_S.
