abstract:

    line_1:        In spite of extensive efforts only two definite
    line_2:        (Crab and Vela) and one probable (in SNR 0540-693)
    line_3:        radio pulsars have been detected at optical
    line_4:        wavelengths.  Most efforts at modeling the optical
    line_5:        emission mechanism are constrained only by the Crab
    line_6:        Pulsar observations. To provide better model
    line_7:        constraints, visual and ultraviolet observations of
    line_8:        the Crab, Vela, and LMC pulsars will be obtained
    line_9:        (see HSP 1101).  The HSP recently acquired high time
    line_10:       resolution data of the Crab pulsar in the visual.
    line_11:       Before choosing the central wavelength and width of
    line_12:       several ultraviolet filters, an exploratory
    line_13:       observation of the Crab in a broad-band UV filter is
    line_14:       necessary.

  question:        3
    section:       1
    line_1:        Crab Pulsar - Observe through a UV filter for the
    line_2:        maximum time possible in one orbit.  Total time: 20
    line_3:        minutes for the Mode II acquisition in one orbit,
    line_4:        and about 40 minutes of high speed photometry in the
    line_5:        next.  Total: 1.0 hours (2 orbits).

  question:        4
    section:       1
    line_1:        The Space Telescope, besides the obvious access to
    line_2:        the UV, provides an opportunity to examine pulse
    line_3:        shape and phase as a function of frequency with lower
    line_4:        sky background levels, better discrimination against
    line_5:        nebular contamination and lack of scintillation noise.
    line_6:        Significant improvement over ground-based data is
    line_7:        expected.

!

  question:        6
    section:       1
    line_1:        Relating Space Telescope observations of pulsars to
    line_2:        previous ground-based data will, in some cases,
    line_3:        require calibration of the Space Telescope clock to
    line_4:        +/- 10 msec to enable phase comparisons. This can be
    line_5:        done after the observations.

!

  question:        13
    section:       1
    line_1:        To assist in selecting filters, bandwidths, and
    line_2:        exposure times for HSP 1101, high speed UV
    line_3:        photometry of the Crab will be obtained.
