The line_2: observations consist of WAVE observations before and after line_3: the SAA, and blocks of 2 minute DARKS in the SAA. We will line_4: work our way into the SAA slowly, and eventually will go line_5: through the heart of the SAA. We will examine both DARK line_6: counts due to the high radiation, as well as flouresence line_7: of the PRISM. line_9: Revised 6/6/89 to match new proposal instructions. line_10: Revised to accommodate proposal meeting 1/5/90 - Oll. ! ! end of abstract general_form_proposers: lname: BAITY fname: WILLIAM inst: UNIV.
