Description:
Illumination by the Sun of each face of the comet 67P/Churyumov-Gerasimenko based on the shape model
CSHP_DV_130_01_LORES_OBJ.OBJ. The service provides the cosine between the normal of each face (in the same order as the faces defined in the shape model) and the Sun direction; both
numerical values and images of the illumination are available. Each map is defined for a given position of the Sun
in the frame of 67P (67P/C-G_CK). Longitude 0 is at the center of each map. The code is developed by A. Beth,
Imperial College London, UK and the service is provided by CDPP (http://cdpp.eu). Acknowlegment: The illumination models
have been developed at the Department of Physics at Imperial College London (UK) under the financial support of STFC
grant of UK ST/N000692/1 and ESA contract 4000119035/16/ES/JD (Rosetta RPC-PIU). We would also like to warmly
thank Bernhard Geiger (ESA) for his support in validating the 2D-illumination maps.

Description:
Images, maps, photometries and other kind of planetary graphic
platforms made by amateur astronomers. Data is received by the
astronomers themselves and can be subject of change
*** EUV-SYN *** Synchronous synoptic maps of the corona in the
extreme-UV (EUV), built from series of SoHO/EIT observations, in each
of the 4 wavelength bands of the instrument.
Synchronous synoptic maps are maps of the EUV radiance in different
wavelength bands on the full solar sphere, in heliographic
(Carrington) longitude and latitude, where data are taken as close as
possible to a reference time. They capture the state of the corona at
any given reference time by including data taken as close as possible
to this time.
EUV-SYN is available as part of the generic MEDOC interface which is
currently located at https://idoc-medoc.ias.u-psud.fr/. These
interfaces are based on the CNES SiTools2 framework. EUV-SYN is also
available from IDL and Python scripts, using a specialization of the
generic SiTools2 IDL and Python clients developed by MEDOC.
*** 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.
