Proposed layout for the Nihuil site
Each eye on the perimeter would presumably have somewhat more than
180 degrees azimuth coverage in order to see showers coming into
the array on the edges. Suppose there are 7 telescopes (210
degrees azimuth) for each partial eye, and 12 telescopes (360
degrees) at the central full eye. The total is then 33
telescopes, slightly less than the 36 that would be used in the
The altitudes and coordinates of the FD sites and other
landmarks have been given by Filevich.
The figure has been copied from a xerox map with overlay
by Alberto Filevich. The plan was developed at the
Itacuraca meeting by Rosanna Cester and Daniel Camin with
help from Karl-Heinz Kampert and others.
Prototype fluorescence detector work would be done on the
hill Los Leones, overlooking the prototype tank array.
The sketch indicates a location for the "central site" (or,
more accurately, "observatory home base") near Los Leones.
Daniel Camin, after visiting the site, has proposed that this
facility be built just north of Malargue instead. An arrow in
this map of Malargue indicates the
proposed alternative location. Some photographs
show some potential sites.

The lake in the lower right part of the figure is not
suitable for tank deployment. It will presumably constitute a
"hole" in the array unless the array perimeter is adjusted to
gain that area somewhere else.
