The gondola was later used for ground-based observations as the MAT/TOCO experiment; so named because the instrument was called the Mobile Anisotropy Telescope and it was positioned at Cerro Toco in the ChileanAndes. It was the first such experiment to localize the position of the first acoustical peak in the CMB.
