Normalised spectra of YSOs classified based on the absence of 12CO (2, 0) band absorption line and presence of Brγ emission or absorption line. Dashed lines and shaded areas represent the central wavelengths and range of continuum used for measuring equivalent widths of Brγ, 12CO (2, 0), 12CO (3,1 ), and 12CO (4, 2) bands. The SST GC No. for each source is specified adjacent to the corresponding spectra.
