<b>GAIA-DEM</b><br/>
GAIA-DEM is a database of Differential Emission Measure (DEM) maps. The DEM is a
measure of the thermal structure of the coronal plasma, representing the quantity of
light emitting plasma along the line of sight, at different temperatures. In GAIA-DEM, the
DEM is modelled by a specific function of temperature, namely a Gaussian of the
logarithm of electron temperature. GAIA-DEM maps are then maps of the DEM
maximum temperature, of the DEM integral (total Emission Measure), and DEM width (in
temperature). These maps are obtained by inversion from the SDO/AIA EUV images in 6
coronal channels (9.4, 13.1, 17.1, 19.3, 21.1, and 33.5 nm). In addition, maps of the χ²
for the inversion are provided.<br/>
GAIA-DEM is available from a specific interface at
<a href="http://medoc-dem.ias.u-psud.fr/">http://medoc-dem.ias.u-psud.fr</a>, as
well as part of the generic MEDOC interface which is currently located at
<a href="https://idoc-medoc.ias.u-psud.fr/">https://idoc-medoc.ias.u-psud.fr</a>.
These interfaces are based on the CNES SiTools2 framework.
GAIA-DEM is also available from IDL and Python scripts, using a specialization of the
generic SiTools2 IDL and Python clients developed by MEDOC.
SBNAF public database of thermal infrared observations of small
bodies in the solar system. Our database collects thermal emission
measurements of small Solar Systems targets that are otherwise
available in scattered sources and gives a complete description of the
data, with all information necessary to perform direct scientific
calculations and without the need to access additional, external
resources. See the details here: https://ird.konkoly.hu/

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
SOIR/VEX to the updated Venus International Reference Atmosphere
(VIRA), Adv. Space Res. (2015),
http://dx.doi.org/10.1016/j.asr:2015.08.012.
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.
