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 degrees to 1.0 degrees. Interstellar dust is observed to have an emissivity [symbol, see text] nu 1.4+/-0.3 and to correlate with the Infrared Astronomical Satellite (IRAS) 100- map. After removal of emission from interstellar dust, 1.3 hr of integration on a 6 degrees scan yields an upper limit of temperature difference Delta T/T < 2.6 x 10(-5) at a Gaussian autocorrelation function centered at 0.5 degrees. The experiment and data analysis are described.
