\section{Scheduling and support}
{\bf A - Coordinated observation:} \\ 
 {\scriptsize\noindent Please indicate if you are planning
coordinated observations with other facilities. \par}


% Please specify coordinated obervations above this line
%-------------------------------------------------------
\vfill
{\bf B - Impossible Dates:}\\
%{\scriptsize In order to make most efficient use of observing time in
%view of personnel limitations, the number of reconfigurations of the
%telescope and its instrumentation will be limited.  We therefore will
%group observing requests of similar technical nature into combined
%periods.  An attempt will be made to accommodate a very limited amount
%of ``impossible time'' in the schedule.  There is absolutely no
%guarantee for success of this attempt.  Please keep this in mind when
%specifying your restrictions above these lines.  Please keep also in
%mind the possibility of having your observations made by a colleague in
%cases of time conflicts.  Thank you for your cooperation. \par}

%{\footnotesize\noindent This part shall be completed on line through our website at

{\footnotesize{\bf  Note for 2025 users:} \\
	A word on 2024 known problems and solutions:
	\begin{itemize}
		\item[-] The optical diffusion problem that was detected in Sept 2024 (mostly affecting the He D3 observations) has been identified and corrected (November 2024).  
		\item[-] The data acquisition issue in polarimetric modes was tracked down to a bad sync between the analyzer rotation and the camera exposure. This has been solved at the cost of slowing down the acquisition loop (roughly a factor 2 slower). This issue has been affecting all the September 2024 runs.  
	\end{itemize}
  

{\footnotesize{\bf At this moment (Jan 2025) we propose: :}
\begin {enumerate}
  \item {\bf MTR2 in spectroscopy mode}\\  In this mode we propose up to 4 (old) EMCCD Andor iXon camera (512x512)  and up to 2 (new) Andor Zyla (2kx2k) cameras. Both 6 cameras can be setup and used at the same time (with their respective specs),  in accordance with the SP2 output physical limitations.  
  \item {\bf MTR2 in spectropolarimetry mode} \\ 
  In this mode, {\bf 3 cameras (hence 3 wavelengths) at most} are available, from the above description. It is possible to combine polarimetric and non-polarimetric cameras. \\ 
  Our polarimetric analysis scheme is based on a full-Stokes analyzer located at the F1 prime focus. For any solar polarization state to measure, the output of the analyzer is made of dual superimposed complementary linear polarizations. Thanks to our "polarization friendly" new optical scheme, this output travels through the telescope and arrives unperturbed on the spectrograph cameras. Just in front of the camera, a Wollaston splitter separates the beam into complementary Stokes components to form the spectral focal plane.\\
  Regarding available analysis software:      
   \subitem - A Stokes map quick-look is now available.
   \subitem - Thanks to V. Bommier, a basic magnetic field inversion software package (running locally in IDL) is available. 
  \item { \bf Broadband imaging camera, running concurrently with the spectrograph}
     Nominal setup is for G-band, but this can be changed optionally (current setup is for 650 nm (red))
  \item {\bf Adaptive optics } is available and tested over sunspots and granulation with good results over  significantly long periods of time (seeing dependent).
   \subitem - A slowed-down (100Hz) version of the same system can be used to stabilize Mercury.
   \subitem - At the moment it is not possible to use the AO over the solar limb (or for neighboring prominences).
 \end{enumerate}
 
 \pagebreak
 
 
 
 Please indicate  below your expected technical setup. Remember that a   spectrograph simulator and an acquisition simulator are available at \texttt{https://themis.iac.es/doku.php?id=technical:mtr2} \\
As a minimum, indicate the  spectral wavelengths at which you will be  using the MTR spectrograph and the need for spectropolarimetry.\\
