    To the left is shown the ATMOSPHERIC TEMPERATURE PROFILE (as a function of altitude) and the +/-- 1 σ uncertainties derived from the acceleration measurements obtained during the SPIRIT Lander's Entry, Descent, and Landing on January 04, 2004. To the right is the profile for the OPPORTUNITY Lander on January 25, 2004. See MER1PROFILES (Opportunity Data) and MER2PROFILES (Spirit Data) data files.
