Key Points

This research aims to create a uniform catalogue of projected rotational velocities for M dwarfs to enhance exoplanet detection accuracy.
Applied an oversampled convolution method incorporating a limb-darkening model to calculate projected rotational velocities.
Analyzed 392 M dwarfs using CARMENES with a focus on spectral line broadening techniques.
Compared observed spectra to template star spectra for accurate measurements.
Achieved a median relative uncertainty of 6.8% in rotational velocity measurements, significantly lower than the 15.4% previously reported.
Developed the largest uniform catalogue of projected rotational velocities from CARMENES spectra, including 36 new targets.
Identified updated values for rotational velocities and upper limits for various M dwarfs.
