Spectral Data for Figures 1 and 2 of "Gravity-sensitive Spectral Indices in Ultracool Dwarfs: Investigating Correlations with Metallicity and Planet Occurrence using SpeX and FIRE Observations"

This dataset contains the near-infrared spectra used to generate Figures 1 and 2 in the paper "Gravity-sensitive Spectral Indices in Ultracool Dwarfs: Investigating Correlations with Metallicity and Planet Occurrence using SpeX and FIRE Observations," submitted to AAS Journals. The spectra include observations of M and L dwarfs obtained with the SpeX/SXD (R2000) and FIRE (R6000) instruments. Each file provides wavelength, flux, and flux uncertainty information in CSV format. The spectra are continuum-normalized for comparison and analysis purposes. This dataset is shared in accordance with the AAS Journals' data-sharing policy and is intended to support transparency and reproducibility of the published results.
