Purpose of the flight and payload description

A balloon-borne instrument to make measurements of the cosmic microwave background (CMB) anisotropy on angular scales between 0.5 and 3 degrees. The experiment uses a one meter, off-axis Cassegrian telescope, coupled with a four spectral band radiometer. The pointing for the experiment is controlled by a platform which was originally built in the early 1980's by a group at GSFC to map the Galactic plane (FIRS instrument).
