> The goal is to determine the air pressure back then to within an accuracy of 0.1 bar (the current atmospheric pressure is approximately equal to 1 bar ).

С точностью 0,1 бар.

>Roger - Well, it us tells that the maximum possible atmospheric pressure was about 1.6 bars, so 1.5 times what it is now, but more likely, it was 1.1 bar, 1.1 atmospheres, well maybe even as low as 0.6 of a bar, so only 6 tenths of our current atmospheric pressure.
