| Because of the height of the THEMIS spectrograph, about 50 meters of cables are needed to connect the THEMIS control room with the different systems of the telescope and its instrumentation. These cables are used to power the mount and the different motors, to send commend to the telescope and to receive housekeeping and scientific data. This image of the month presents THEMIS cable reel and ill-known although fundamental element for the operations of THEMIS. A specificity of THEMIS is that the whole THEMIS instrumentation hangs under the THEMIS mount and rotates with it as the telescope tracks the Sun. THEMIS cable reel, located at the 4th floor of the THEMIS building permits to avoid the tearing out of the cables as the telescope rotate. About 6 meters of cable length are "stored" within it, compensating the lengthening of the distance as THEMIS moves. | A summary figure of THEMIS level 1 [[observation:data | data products]]. These are the datasets that are directly generated during an observation with THEMIS. The full Sun and slitjaw images are context images that are mainly used to have basic information of the solar condition on the Sun and the location of the high resolution observations. They are not really meant for scientific use, as equivalent data of a better quality can be obtained by other instruments. The main scientific data are the [[observation:data#Broadband images (BBI)| broadband images]] to study the dynamics of the solar photosphere at high-cadence and high spatial resolution, and the [[observation:data#Spectral images]] from which physical properties such as composition, density, temperature, velocities and magnetic field of the emitting solar plasma can be derived. |
