Well, at least the schematics have degrees labeled. :}(whatever emotion that is supposed to be is what I mean to convey)

For those unaware when the MIRI MRS (mid resolution [integral field] spectroscopy) mode is called for, often times the imager is simultaneously used for astrometric correction. (That is, by imaging (visually) nearby stars it’s possible to determine exactly where the observed MRS field is located.)

This piece is really as far as anyone as has pushed 13-limit extended JI and probably as far as anyone will push it. You can easily rack up more pitches but being able to return to normal pitches without forced respelling takes a level of sophistication no living person has to my knowledge.
