Left: comparison between visual-wavelength spectra of the Type Iax SNe 2008ha (black) and 2010ae (red) taken around maximum light and a fortnight later. The spectra of SNe 2008ha and 2010ae have been corrected to the rest frame adopting redshift values z = 0.0047 and z = 0.0037, respectively. The spectra of SN 2010ae have also been de-reddened for an E(B − V)_tot = 0.62 mag. Telluric features are indicated with an Earth symbol. Right: comparison between NIR spectra of the Type Iax SNe 2005hk (black) and 2010ae (red) obtained around maximum light and several weeks later. The spectra of SNe 2005hk and 2010ae have been corrected to the rest frame adopting redshift values z = 0.0130 and z = 0.0037, respectively. Vertical gray bands mask the most prevalent telluric absorption features.
