At ground-based resolution its core line_3: profile is unresolved. B and V exposures with the FOC should line_4: reach far enough down the main sequence to distinguish stars line_5: of different mass. The three FOC fields are the center and line_6: two neighboring regions. line_8: Simultaneous exposures are made in V and I with the WFC, to line_9: gain further structural information. These will go much line_10: deeper, since the orientations are arranged so as to keep the line_11: WFC on the same field at all times. ! ! end of abstract general_form_proposers: lname: KING fname: IVAN mi: R. inst: UC, BERKELEY country: USA ! lname: MACCHETTO fname: F.

Since parallel observations are line_3: required, the program can be done only in 1992. If line_4: necessary, it can be allowed to slip into the early part of line_5: Cycle 2. line_7: Although line 11 is outside the normal GS-reuse limits of 2 line_8: arcmin and 3D ORIENT, plotting of GS and apertures shows line_9: that it easily fits with the original GS. Thus this entire line_10: program should be taken with a single GSACQ. ! question: 6 section: 1 line_1: GROUP allows 7 primary exposures on a single guide-star line_2: acquisition.
