Selected SpT indices from the literature versus the NIR SpT derived via a direct comparison with spectral templates. The classes young, mid-gravity and field from the dataset of AA22 are represented as orange, blue and gray circles, respectively. The black solid lines represent the sensitivity range of each index (see Table 4). The black arrows demonstrate the effect of 5 magnitudes of extinction on the index values.
