Spectrum for HD 133778B. Both the IFS (YJ) and IRDIS (H) bands are shown. HD 133778 shows a good match to spectral types ∼M3–M4, which is in agreement with the absolute magnitude of this object. Reference spectra are from Cushing et al. (2005), and the stars used as reference objects for M1 to M7 respectively are GL229A, GL411, GL388, GL213, GL51, GL406, and VB8.
