Have you got your target lists ready ?

1) get the tarball;
2) unpack it in your working directory;
3) choose the appropriate executable for your machine. Binaries are provided for RedHat Linux, Digital Unix, and SunOS (statically linked). If you do not have access to a workstation running one of these operating systems, please contact the TNG Staff Astronomer.
4) Read the MOS blind-mode instruction page and the detailed HOWTO, have a look at the EXAMPLES directory, and try TNG_MASKS yourself. Enjoy !

Please request the most recent version of the TNG_MASKS executable code for Linux, DEC/Unix, and SUN/Solaris to the DOLoRes Staff Astronomer.
