[ASTRO\]OBSERVATORY [longitude latitude altitude [radius]]
[ASTRO\]OBSERVATORY [Name] [Version] [Mode]
Specify an observatory by giving its geographic coordinates in degrees,
and elevation in km above sea level. Caution: east longitudes are posi-
tive. The fourth argument is the radius of the Sun avoidance circle, in
degrees (default is 30 degrees).
Example: OBSERVATORY 44:23:12.0 +45:09:57.9 3.987 30.
A number of observatories are pre-defined and can be selected directly
be typing "OBSERVATORY Name". Type "OBSERVATORY ?" for the list of known
Without argument, the observatory name is translated from the GAG_AS-
TRO_OBS logical name.
For NOEMA, PDBI, and ALMA, a version can be added as argument. This can
be used to select the instrument capabilities, as done by SELECT
PDBI|ALMA command in the past.
For NOEMA, there is only one year possible for the time being (2017). In
ASTRO, the switch to NOEMA observatory name has been placed at the de-
livery of the NOEMA backend polyfix.
For PDBI (observatory can be PDBI or BURE), a year must be entered:
1995, 2000, 2006, 2010, 2013, or 2015. They correspond to the upgrades
of the receiver system (1995, 2006, and 2015) and of the correlator
(2000, 2010, 2013).
For ALMA, the cycle number must be entered (0, 1, ...). Any number larg-
er than the current cycle is equivalent to "OBSERVATORY ALMA FULL" and
points to the full ALMA capabilities.
For NOEMA, PDBI, ALMA, and 30m, OBSERVATORY also enables some specific
commands to define and visualize receiver and backend configurations.
These commands are gathered together in the dedicated languages NOEMA\,
PDBI\, PICO\ and ALMA\ (see e.g. HELP NOEMA\ for the list of available
