map obtained 
the December 8th, 2001
with the thermal source 
placed on Radar Hill (~1 km).

bolometers are separated
by ~ 30', beams ø ~8 to 10'.

545K01 cannot see the source 
because the atmosphere
is opaque at this frequency 
(water vapor absorption).

353K01 & 353K02 ,
353K03 & 353K04,
353K05&353K06
share the same horn
(polarized bolometers).

217K03 (which should be
beside 143K07) is outside the map. 

143B03 is blind and 
see the 10K stage.
