And for potential newcomers:

Rules of the instrumentation group meeting are:

1. Send 2 slides about what kept you busy this week to me and Michiel at haffert@strw.leidenuniv.nl mailto:haffert@strw.leidenuniv.nl and m.darcis@sron.nl mailto:m.darcis@sron.nl . 2. Each slide needs to contain at least 1 picture. This can be a screenshot of whatever. For example, a screenshot of homework, a paper you have read or even a picture of your cat or dog. 3. You can use these slides to introduce yourself if you are coming for the first time. 4. The rules don’t apply if you have a PhD. But, I still like to see something.

Hi all,

We have been blessed with presentations lately, but this week is a classic instrumentation meeting with slides, slides, and you guessed it, slides. Therefore, send in your two slides to haffert@strw.leidenuniv.nl mailto:haffert@strw.leidenuniv.nl and m.darcis@sron.nl mailto:m.darcis@sron.nl and I will see you at 11 in the Oort room.

Cheers,

Michiel
