In this page there are listed all the LIRIS masks that are currently stored in the bookshelves from the Astronomy office (first floor of the WHT building).
Last survey of the stored masks was made by Cecilia Farina during the 1st Dec 2015. It that opportunity it was checked the masks conditions and features and that the name on the mask is the same as the name in the box and name in the plastic bag where the masks are stored.
If you need to put masks here or take a mask out or you see something unusual related with the Archivadores please contact the LIRIS MOS Instrument Specialist to inform.
