Stark units for some newforms

[Arnau Padrés Masdemont]

Hi all,

For a project, I computed several Stark units for newforms of weight 1 of dihedral (D_n), tetrahedral (A_4) and octahedral (S_4) type, which are listed in the attached pdf. Is this data already known? If not, is it useful?

Maybe it can be used to find Artin images, which are not in LMFDB for octahedral newforms, I am not sure. Also, I could probably find more cases of the three projective types with the same method. The notation in the tables is the same as in Ch. III, $4 of the book 'Les conjecture de Stark sur les fonctions L d'Artin en s0' by John Tate. 

If this is not useful, please just ignore this email,
