Happy new year to all of you, too, and best recoveries from your =20 injury, Fabien!

Does this mean that that the spectral type is > determined as a composite, and the result is M1? According to hip_main.dat, the spectral type of HP24608 is "M1: comp =20 ", whatever this means. The source for the spectral type is currently the Hiparcos catalogue: =20 hip_main.dat and errata.htx. So there is no obvious mistake, and I am unsure what to do. The easiest =20 possibility is leaving it as it is, and saying that the spectral type =20 is correct according to the Hiparchos catalogue. Anyway the spectral =20 type has no influence on the color, when B-V is given, as in this case. Johannes |
