Summary of the characteristic of the grisms+CCD setting most commonly employed for magnetic field measurements.

Grism	CCD	Wavelength	Dispersion	Resolution
		range (Å)	Å pixel^-1	(1′′ slit width)

600 B	TK2048	3480–5900	1.2	830
600 B	EEV	3400–6100	0.75	810
1200 g¹	TK2048	4290–5470	0.58	1725
1200 B	EEV	3660–5110	0.36	1540
600 R²	TK2048	5250–7415	1.2	1230

Notes.

⁽¹⁾

We note that grism 1200 g was often used setting the slit close to the right edge of the instrument field of view. For that special setting, the observed wavelength interval was 3840–4970 Å.

⁽²⁾

Grism 600 R was used together with order separation filter GG 435.
