Gaia's data archive, how to use it

[Astrofriend]

It's hopeless in Sweden where I live, rain and rain and clouds.

I have to do something about it. I have already earlier used some data from astronomy data archives. Now I start with a new satellite, the Gaia astrometry satellite. It doesn't have images, it has astrometry data.

There are a lot of interesting things that can be done with these data. But first I have to learn how to extrat the data from the archive and how to process it.

I have written down how I do it and can be used as a tutorial for you who find it interesting.

Here it is on my homepage:

My first calculation is a HM-diagram of the stars close to the Sun.

Hope you find it as much interesting as I do.

Hi,
With a lot of free days at Christmas I have added more information of how Gaia data can be used. Plots of velocity and position, more will added in the future. In the learning process to do more advanced things later.
