abstract:

    line_1:        The puropse of these observations is to obtain high resolution images
    line_2:        of the asteroid Ceres with the present HST. All information given in the
    line_3:        general form text pertains to pre-spherical aberration; observations
    line_5:        as described there (DECON and ROT) will be carried out in Cy 9.

  question:        3
    section:       1
    line_1:        A) DECONVOLUTION: The goal of these observations is to increase the resolution
    line_2:        of the ST/FOC by image processing techniques. For this purpose exposures
    line_3:        have to be taken with different ST roll angles, spaced as closely as possible
    line_4:        in time.
    line_8:        the rolled exposure can only be taken one orbit after the unrolled exposure.
    line_9:        This time line should allow the determination of the direction of the rotation
    line_10:       and of the pole axis, plus a confirmation of the potometric rotation period.
    line_11:       One of the priority 1 objects shall be observed during cycle 1.

!

  question:        4
    section:       1
    line_1:        The FOC at f/96 provides the required resolution.

!

  question:        5
    section:       1
    line_1:        Asteroids have to be observed close to opposition. The scheduling of the
    line_2:        observations is therefore closely tied to the ST launch date and to the
    line_3:        availability of the moving target acquisition mode. We expect to work closely
    line_4:        with the schedulers at the ST ScI.

!

  question:        7
    section:       1
    line_1:        Quick-look data analysis will be carried out at the STScI immediately following
    line_2:        the observations.
    line_4:        Final data analysis will be carried out at the European Coordinating Facility,
    line_5:        and at the computer installations of the home institutions of the other
    line_6:        proposers.

!

  question:        10
    section:       1
    line_1:        Our institutions will supply the following resources:
    line_3:        Salary, travel, data analysis facilities, research support, administrative
    line_4:        support, office space.

!

  question:        13
    section:       1
    line_1:        The purpose of this investigation is to determine physical properties of
    line_2:        selected asteroids: diameters, shapes, surface structure, spin axis
    line_3:        orientation, rotation, and possible binary nature.
