        <description>THEMIS team &amp; institutional structure

Actual THEMIS team 


THEMIS activities are managed thanks to a dual administrative structure: 

- THEMIS S.L.U, a private spanish company owned by the French CNRS INSU. 

- The French-Spanish Laboratory for Astrophysics in Canarias (FSLAC; CNRS IRL2009), a joint international research Laboratory between  CNRS INSU and the  Instituto de Astrofísica de Canarias (IAC).

The full archive until 2014 is stored  on DLT tapes at the telescope. We do have a functionnal tape reader but no usable software to run it.

We maintain an incomplete archive of years 2009, 2010, 2012, 2013, 2014 on HDDs. Listing of what&#039;s available:

        <description>Themis An4 analyzer principle

Themis An4 new polarimetric analyzer is a dual beam full-Stokes analyzer. The “modulator” part is made out of two quarter-wave plates and is quite similar in its principle to our former An2 (it actually uses the  very same sets of crystaline retardance plates) or An3 (this version, while identical in the principle, was using twisted nematics LCDs retarders). The $\varphi$$$M_0(\varphi) = \left(\begin{array}{cccc} 1 &amp; 0 &amp; 0 &amp; 0\\ 0 &amp; 1 &amp; 0 &amp; 0\\ 0 &amp; 0 &amp; \cos\!\left(…</description>

        <description>Inline math tests (mathjax plugin) 

This is is a test:  $a^2 + b^2 = c^2$           

This is another test: \(1+2+\dots+n=\frac{n(n+1)}{2}\)

To display math on its own line, use double dollar signs:

 =&gt; $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$ 

gives:
$$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$

or escaped square brackets: \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]$\hat T_p$\begin{equation}

        <description>2020 Observing schedule (May update)

Following our 2020 call for observing time, a schedule was ready by the beginning of march with observing runs starting in june and until the end of the year. This agenda is now obsolete because prior to the observing campaign, mandatory technical actions and commissionings were due to take place in march/april/may, that it has not been possible to fulfill so far:

        <description>THEMIS publications library

Here we count the publications making use of the THEMIS telescope or of data acquired by THEMIS instruments. Some publications use only THEMIS data, but many use several data sources to get to the result. An acknowledgement of the use of the THEMIS telescope is mandatory in any publication using any fraction of THEMIS data, however this rule has been diversely followed over the years. Identifying a publication for this list is based on the existence of such acknowled…</description>

        <description>THEMIS Solar Telescope

The “Télescope Héliographique pour l’Étude du Magnétisme et des Instabilités Solaires” (THEMIS) of CNRS-INSU is a 1-meter-class optical solar telescope, primarily dedicated to studying solar magnetism and the dynamical processes within the Sun’s atmosphere (such as sunspots and solar flares). THEMIS can also perform observation of near-Sun objects such as Mercury and comets.  &lt;a href=&quot;https://www.themis.iac.es/lib/exe/fetch.php?media=science:gallery:building:themis_winter…</description>

        <description>TAO (Themis Adaptive Optics) 1st light

TAO stands for THEMIS Adaptive Optics. It is made of a classical solar AO hardware currently running at 1 kHz and combining a Shack-Hartmann wavefront sensor with 76 subapertures (10×10 geometry) and a deformable mirror DM97 from ALPAO with 97 actuators. See
