Firstly, thanks Maxim for the interesting little search puzzle, I couldn't resist it.

Is it just the spectral types (just the colours) you wanted, or the full MK? I'll presume the former. It seems they vary quite a bit, depending on the source, but I think it is safe to say that the newer Hipparcos/Tycho data is the most accurate. You can judge for yourself. Maybe someone else who knows better can advise.

Below is an extension of your list, where "C. de ciel" is the planatarium software Carte de ciel, "HNS" is the software Hallo Northern Sky, SIMBADs' link is here http://simbad.u-strasbg.fr/sim-fid.pl and V 2.1a is the extended star dataset I use with Celestia (found here, in case you don't know about it) http://perso.wanadoo.fr/celestia.stars/index.html (thanks to Pascal Hartmann).

* Also known as TYC 4037-2624-1
** Also known as TYC 1839-732-1
^ Also known as TYC 1333-1683-1
^^ Also known as TYC 173-3208-1

Carte de Ciel use the Sky2000 master sky catalog, Hallo Northern sky uses the SAO complete catalog, SIMBAD and V2.1a uses Hipparcos data, as far as I can make out.

Hope this is of some help to you.

Thanx Losty,

That'll help me.
What I have is a set of absortion spectra images for those stars, that'll show a comparision of spectra along the main sequence with some extra examples for metal poor variations. I'd like to put these into a info-plugin addon, so they can be accessed directly with the 'info' menupoint of that star. My list above showed what I've found in Celestia, and how that differs from what is given by the images data.

I didn't know the alternate star names. The two last that are missing will have to be inserted by .stc I think - as soon as I've collected the definition data. If someone has them on his fingertips ...
