performance question?

[Anon]

Hi I'm writing a weather web site using PHP/MYSQL.

My table has parameters like day, max, min, weather. These parameters will change on a daily basis, BUT I also have parameters like
lat(for latitude) and long (for longitude), plus a few other constants.

So my question is, should I have a separate table called constants to store these values, then call them when needed?

or would it be better to have them all in one table?

Thanks
