Proposal_Information Title: 3 POINTS OF LIGHT CALIBRATION Proposal_Category: CAL/AST Scientific_Category: Cycle: 5 Investigators PI_name: LATTANZI, MARIO G.

Questions Observing_Description: Obtain 7 consecutive Transfer scans through each of 3 filters at the 3 specified positions in the field of view. Real_Time_Justification: Calibration_Justification: Additional_Comments: Abstract: The purpose of this proposal is to obtain reference Transfer Functions through three filters (PUPIL, CLEAR and NEUTRAL DENSITY) at each of 3 points in FGS #3 (the astrometer). These Transfer Functions will be used to deduce the presence of secondary stars in multiple systems, and to calibrate the non-zero angular diameter of extended sources. The 3 points are distributed azimuthally along the midline of the field of view. The standard FGS calibration target, Upgren 69, will be observed through the F583W, PUPIL and F5ND filters at each of the 3 points.
