Abstract (from CDS):

Using a volume-limited sample of 263 field-age brown dwarfs defined by parallaxes, we provide updated polynomials for CatWISE W1 and W2 absolute magnitudes as a function of spectral type. Our fits are consistent with previous relations and apply to a wider M6-Y1 spectral type range.
