abstract:

    line_1:        This is a new proposal submitted in March, 1992 to define
    line_2:        PC exposures of the core of Eta Carinae. The
    line_3:        new PC images include explicit exposures of a nearby star
    line_4:        for the purpose of deriving a valid PSF. The orientation is
    line_5:        specified to allow Eta Carinae itself to remain visible on
    line_6:        the PC when the pointing is shifted to position the PSF star
    line_7:        on PC6. The images are made in a line free violet continuum
    line_8:        and in a line free red continuum F631N (this is a O I line
    line_9:        filter, but there is negligible O I emission in the core of
    line_10:       Eta Carinae.)
    line_12:       This proposal uses GTO baseline time.

  question:        3
    section:       1
    line_1:        Lines 100 - 180 PC exposures of core of Eta Carinae in
    line_2:        violet and red continuum F336W and F631N (no OI in Eta Car)
    line_3:        exposure times based on cycle 0 exposure levels
    line_4:        position target near center of PC 6 - away from bad column.
    line_5:        Lines 200 - 280 exposures of nearby star for PSF measurement
    line_6:        at same position as Eta Car on PC6. The specified
    line_7:        orientation will allow Eta to still be visible on the PC.
    line_8:        These images are primarily for the purpose of studying the
    line_9:        very inner regions of Eta Carinae. They will also give good
    line_10:       information about the Homunculus as it appears in scattered
    line_11:       continuum light, but will not be well suited for studying
    line_12:       the fainter outer condensations.
    line_14:       Each filter has a short and three longer exposures.
    line_15:       Short will give 3000 cts/pixel at peak of image.
    line_16:       Long will give good S/N in wings of PSF without blooming core.
    line_17:       Offset by 1/2 arc sec between longs to sample dfferent pixels.

  question:        4
    section:       1
    line_1:        Spatial resolution needed to study inner core and small
    line_2:        scale structures in Homunculus, and to measure displacements
    line_3:        and proper motions of outwardly moving ejecta.

!

  question:        5
    section:       1
    line_1:        Orientation requested for PC images will allow the PSF
    line_2:        star to be measured on PC6 at the same position that the
    line_3:        core was recorded. At the same time, Eta Car itself and the
    line_4:        Homunculus will still be visible on PC8, 5 or 7. This will
    line_5:        give additional exposures of the primary target with no
    line_6:        additional observing time. If the special orientation is
    line_7:        not used Eta Car would likelly be out of the field of view
    line_8:        during the PSF exposures.

!

  question:        7
    section:       1
    line_1:        Images will be calibrated and deconvolved using the special
    line_2:        psf star. The objective is to study the multiple cmponents
    line_3:        visible in the core in violet and red light, free of nebular
    line_4:        emission lines. We will analyze the relative positions and
    line_5:        brightnesses of the components, and try to detect proper
    line_6:        motions relative to the brightest member. These images will
    line_7:        provide a good baseline for future monitoring of the evolution
    line_8:        of the  core of Eta Carinae. The astrometric reference stars
    line_9:        of Walborn, Blanco, Thackeray (1978, Ap.J., 219, 498) will be
    line_10:       used as the primary position standards. Motions of individual
    line_11:       knots within the Homunculus will also be measured.

  question:        9
    section:       1
    line_1:        An early set of WFC and PC images were obtained in cycle 0
    line_2:        as part of GTO proposal 1186. Our preliminary analyses were
    line_3:        described in the proceedings of the STScI wrkshop on mass loss,
    line_4:        and in a poster paper at the Atlanta AAS meeting in January,
    line_5:        1992.
