== Instrumental modes ==


  * **MTR2**\ \ \ ("MulTiRaies")\\ This is the long slit spectropolarimetric mode of our spectrograph. 

  * **MSDP**\ \ \ ("Multichannel Subtractive Double Pass")  \\ This is a 2d spectropolarimetric mode based on a double pass with 9 wavelength channels and polarimetry.  Here is a basic description of the {{:ugi:dpsm_instrum_2006.pdf| MSDP concepts}}

  * **TUNIS**\ \ ("Tunable UNiversal Imaging Spectrograph") \\ This is a 2d spectroimaging mode also based on a double pass with only one channel and different features than MSDP.  

== Software ==

  * The SQUV package
  * DeepStokes
  * INVFe
