Encyclopedia
QMAP is a balloon experiment to measure the anisotropy of the Cosmic microwave background. It flew twice in 1996, and was used with an interlocking scan of the skies to produce cosmic microwave background (CMB) maps.
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
