Actually, IMO the obligation of instructor to student are stronger than a mere business-customer relationship, but I am told I have quaint, if not downright obsolete, opinions about how academics should behave.

 

I'm not sure I've encountered a colleague who "forgets" their obligations to students. There's been lots ... even me at times ... who finds course grades after the term to be a nuisance, but that's reason to rush through it, not to blow it off entirely.

I have a bottle of 12 year old single malt Jameson's I'd happily share' date=' but you're a bit far away. Though next time you're in the SF Bay Area...[/quote']

 

Many thanks, but I'm well stocked for this weekend. With the temperature predicted to get only to about 70 F, I won't even need as much ice as I anticipated.

No, I would probably agree with you. Teachers have some of the greatest responsibilities in society, right after parents.

That was exactly my feelings and response as well. I just wanted to hear it from an actual professor. To me it was the same thing as me telling a customer' date=' "I'm sorry, I won't be able to help you because I have other tasks I need to do." Students are the customer at a university, and I think that some professors forget that.[/quote']

 

And I think there is an implicit contract involved. The professor would be in breach of contract.

My flat-text file has a couple of catalog numbers, parallax with its standard error, apparent magnitude, absolute magnitude, celestial coordinates in funny units, and spectral type. The full HIPPARCOS catalog has more data than that, but I cut it down to the bits most useful for gaming.

Two flat-text files, 679k and 635k respectively. Though I'm almost certain you can find the same data on the Web already. I seem to remember Nyrath having it somewhere on his complex. And if you know what you want, you can get the data from the Vizier site.

 

What isn't in them is the fancy names. Getting those is annoying, but there's only a few hundred of them.

---------

Tab-separated (so the forum software suppresses the tabs and you lose the spacing). First column is HIP (Hipparcos number). Second column is apparent V magnitude. Third column is right ascension in degrees, fourth column is declination in degrees; both are for the epoch of the Hipparcos catalog, which is 1992 or so. Then comes the parallax in milli-arc-seconds, and then its standard deviation in the same units. The next column, if there's data in it, is the HD number of the star (HD being a long-standing nearly comprehensive catalog of spectral types of stars down to about 9th magnitude or a little fainter). Then comes the spectral type of the star, taken from a variety of sources (those are sort of "use at own risk" data. The last column is the absolute visual magnitude computed from the V magnitude and the parallax.

 

Yes, I sorted things in decreasing order of parallax, which is equivalent to increasing distance. The distance in parsecs is 1000/(parallax in arc seconds). Multiply by 3.26 to get light-years.

 

Those first six stars are, respectively, Proxima Centauri, alpha Centauri A, alpha Centauri B, then two nameless M dwarfs, then Sirius A.
