Paper Abstract

The Center for Astrophysics-University of Arizona balloon-borne, inertially-guided, 102 cm telescope was designed to perform photometry and high resolution mapping of far-infrared (40-250 um) celestial sources. To date the telescope has now been flown and successfully recovered a total of ten times. Six of the flights have produced useful astronomical data, resulting in more than 40 hours of observations of numerous objects, such as HII regions, dark clouds, molecular clouds, galaxies, the galactic center, planets, and an asteroid. Maps with a resolution of 1 arcmin FWHM have been achieved with absolute position accuracies of ±10 arc-sec. The rms noise equivalent flux density of the system is ~70 Jy/(Hz)1/2. From the launch site in Texas, sources as far south as -50 degrees declination have been observed.
