Description:
Profiles of species in Venus atmosphere terminator. Data retrieved
from calibrated spectra obtained with the SPICAV-SOIR instrument on
board the Venus Express spacecraft. These spectra can be checked on
the ESA PSA repository. See: A.C. Vandaele et al., Contribution from

The Multimission Archive at STScI is a NASA funded project to support and provide to the astronomical community a variety of astronomical data archives, with the primary focus on scientifically related data sets in the optical, ultraviolet, and near-infrared parts of the spectrum.
The database contains profiles of atmospheric CO2 density and
temperature derived thereof, and ozone concentration profiles, all
derived from the first year(s) of SPICAM UV stellar occultation
observations (Forget et al. 2009, Lebonnois et al. 2006). The database
also includes the full dataset of four Martian years of aerosol
extinction profiles from SPICAM UV solar occultations (Määttänen et
al. 2013).

Within this use case you learn about the difference between intrinsic
linear size and apparent angular size, a difference that is frequently
at the center of astronomical problems. Star clusters are the objects
used to illustrate this difference. You also learn some basic facts
about star clusters, whose distribution in space has helped us to
understand the structure of our Milky Way. Thanks to Aladin, you will
be able to explore their distribution on the sky on your own.
