    "description": "<p>We present a method to derive stellar parameters for M dwarfs using high-resolution H-band spectra via spectrum synthesis using <em>iSpec</em>, <em>Turbospectrum</em>, <em>MARCS</em> models atmospheres, and a custom-made line list including over 1000000 water lines (Sarmento et al. 2021). The method was developed to provide reliable spectroscopic parameters from the spectra of current and future NIR high-resolution spectrographs. We derived the spectroscopic parameters (T<sub>eff</sub>, [M/H], log g) for a sample of 313 M dwarfs in the APOGEE DR16 and compared them to the ones obtained by ASPCAP and previous values derived from NIR and optical data.</p>",
