We welcome correspondence concerning the possibility that data from the
UVCS/SOHO instrument might be useful in your research program. Please
request any information that might help you identify a use for UVCS data in your
research. UVCS is a complex spectroscopic instrument and there are subtle
techniques involved in analyzing the data. Therefore, we enourage you to enter
into collaborations with the scientists already involved in UVCS operations and
data analysis.
In general, UVCS is a spectroscopic instrument
that observes the extended solar corona from about
1.3 to 11.8 solar radii with a spatial resolution
of about 15 arcsec. Often, the spatial resolution
is degraded to improve statistical accuracy. Coronal
holes are observable up to about 4 solar radii and
streamers up to at least 8 solar radii. UVCS can also
observe stars, comets, interplanetary H I, and planets
at projected heliocentric heights up to 11.8 solar
radii, and it can observe from disk center to 1.3
solar radii, although we try not to do that often
because of concerns about detector aging and optics
contamination (polymerization).
UVCS provides ultraviolet diagnostic techniques
to determine velocity distributions for protons,
electrons and minor ions; outflow velocities for
protons, O5+ and other ions, particle densities,
and elemental abundances. We have observed about
31 spectral lines in the extended solar corona
for H I and ions of C, N, O, Mg, Al, Si, S, and Fe.
