We must make low resolution observations line_3: at L alpha at the absorption redshifts to determine whether there is enough line_4: light for the high resolution observations. line_5: The SV prerequisite programs for all FOS observations in this program are: line_6: Prop ID 2195 FOS Target Acquisition Tests All observations line_7: Prop ID 1317 Int./Ext. Wavelength Offsets 1st target line_8: Prop ID 1318 Spectral Flat Fields 1st target line_9: Prop ID 1320 Absolute Spectrophotometry 1st visit of bright targets ! question: 8 section: 1 line_1: We will try to schedule near simultaneous ground based observations if we line_2: are given enough lead time. ! question: 12 section: 1 line_1: Our experience with high z quasars at the Lyman limit suggests that we line_2: will only be able to make half the high resolution observations. This is line_3: reflected in the requested observing time. line_5: Because of the statistical nature of this program, it should not be line_6: considered viable until 75% of the observations have been done. No data should line_7: be released until a year from this date. ! question: 13 section: 1 line_1: FOS spectra will be obtained of 5 quasars with z > 3.1 to examine HeI and line_2: HeII in absorption and/or emission and perform the Gunn-Peterson test for line_3: smooth intergalactic helium. ! !end of general form text general_form_address: lname: BURBIDGE fname: E.
