UV_TRACKS ALMA_ACA

            ---- Using UV_TRACKS for ALMA ----

        UV_TRACKS can be used to simulate ALMA observations,  using  the  /TABLE
        and  /FRAME options to create tables with one or several configurations.
        To do so, the command sequence must be

        OBSERVATORY alma
        SIC LOG astro_stations "alma-current.cfg"
        UV_TRACKS all [...options...]

        The logical astro_stations must point to a configuration file  of  ALMA.
        They  distributed  with  GILDAS and the currently offered configurations
        are named "alma-current-"'J'".cfg" and "aca-current.cfg" where J is  the
        configuration  number.   All the versions of previous ALMA configuration
        files are distributed under the  names  "alma-cycle"'I'"-"'J'".cfg"  and
        "aca-cycle"'I'".cfg",  where  I is the cycle number.  Note that when the
        configuration of several cycles are identical we keep only the files  of
        the  first cycle in which they were offered.  Then "uv_tracks all" means
        all stations will be used.

        For ACA, it is better to enter "observatory aca" - coordinates  are  the
        same, but this will make sure the proper antenna diameter is used in the
        computation of shadowing.
