... The various Inst :Focus scripts allow you to take a series of exposures over a range of secondary mirror focus values, report the resulting FWHMs and optionally adjust the focus to the estimated best value. ... Slitviewer scripts assume the focus star is on the boresight. ... Focus scripts runs in three phases: . ... The script moves the boresight so the focus star is visible next to the slit, sets the focus to Center Focus, takes an exposure and tries to measure the star's FWHM. ...

... For high spectral resolution observations the devices permanently located at the N2 focus of the BTA are used (Klochkova, 1995, Panchuk, 1995).
