Abstract
Preliminary results from the June 1991 flight of MAX are presented. Simultaneous observations were made in bands centered at 6, 9, and 12 cm-1 with a bolometric receiver operating at 300 mK. The experimental sensitivities are the highest reported at angular scales of 0.3° to 1.0°. Interstellar dust is observed to have an emissivity ∝ ν1.4±0.3 and to correlate with the Infrared Astronomical Satellite (IRAS) 100-μ map. After removal of emission from interstellar dust, 1.3 hr of integration on a 6° scan yields an upper limit of temperature difference ΔT/T < 2.6 × 10-5 at a Gaussian autocorrelation function centered at 0.5°. The experiment and data analysis are described.
