The line_6: possibility of variations from pixel to pixel should be reduced by taking three line_7: exposures of each star field with an offset of a few pixels in the image line_8: location at each pointing. Each target field should be observed approximately line_9: every three months during the first year, and at maximum and minimum parallax line_10: positions during the following year. line_12: The observations during the guaranteed time will be the first of a series of line_13: observations of these stars to be taken over the lifetime of the Space line_14: Telescope. In combinations with ground-based observations, improvements to the line_15: parallaxes and proper motions will be investigated. ! ! end of abstract general_form_proposers: lname: WESTPHAL fname: JAMES title: PROF. mi: A. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Each target field should have three exposures with an offset of a few pixels in line_2: the image location at each pointing.

These observations line_4: will be used to determine improved parallaxes and proper motions and to line_5: investigate short or long period motions. The observations should be the first line_6: in a series of observations over the lifetime of the Space Telescope and the line_7: list of target stars may be revised during that time.
