*** GAIA-DEM *** 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 33.5nm). In addition, maps
of the ϲ for the inversion are provided.
GAIA-DEM is available from a specific interface at
http://medoc-dem.ias.u-psud.fr/, as well as part of the generic MEDOC
interface which is currently located at http://idocmedoc-
test.ias.u-psud.fr/. 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/

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
