Identifies the MIRI filter element that was used. The imager's only moving part is an 18-position filter wheel. Filter positions are allocated as follows: 10 filters for imaging, 4 filter and diaphragm combinations for the coronagraphy, 1 neutral density filter, 1 ZnS-Ge double prism for the LRS mode, 1 opaque position for darks, and 1 for a lens for ground test purposes.
