42	Expected % of collecting area in Chile with ALMA	83.3	%
43	% of collecting area in Chile with ALMA for the selected year	83.3	%
44	% of collecting area in Antofagasta with ALMA for the selected year	76.3	%	in relation to world	Please note: Adding ALMA to the calculation and not other radiotelescopes such as FAST
45	% of collecting area in Antofagasta with ALMA for the selected year	91.6	%	in relation to Chile	(500-m diameter dish) makes no sense.
