We will test line_4: the ability of the FOS to detect weak emission lines against line_5: a background of weak absorption lines in a faint object with line_6: the degraded performance due to the slit losses, decreased line_7: resolution, possible increased scattered light and greater line_8: than expected particle-induced background. From this line line_9: we will determine the relative abundance of Helium in the line_10: early universe. ! ! end of abstract general_form_proposers: lname: ASTRONOMER fname: JOE title: DR. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: This proposal contains 1 object which will be observed with line_2: G160L and the red detector of the FOS.
