Sunday 11th March 2018 - Radio Astronomy Group Working Bee

Hi radio astro peeps,

Last Sunday Adrian, Gordy and myself worked on the 21cm hydrogen line gear further, Adrian trying to pin down a hardware fault and myself and Gordy trying to work out the best way of recording data for processing.

You can see us being busy here:

With a first pass at trying to record some sample data here:

Update:

Adrian has been beavering away at the intermittent fault on the receiver and if anyone coming has test gear then it might be useful to him if you are able to bring it along as we try and pin down what's going on.

Last night at MBO I captured about 4 hours worth of data with the eastern (kitchen end) dish and we can look at how that looks and try and understand an odd artifact in it for the first while after it starts capturing data.

I've also had some hints via twitter from an astronomer who deals with hydrogen line data (Benjamin Winkel from Max-Planck Institut für Radioastronomie) about things we will need to consider when processing the data we get. It would be good to look at those ideas and understand what is being suggested and how we can process that data.

So hopefully we can combine some electronics, some data processing and some physics into the session tomorrow.

We will be meeting again for our regular "second Sunday of the month" meeting at MBO this coming 10am Sunday 11th March, feel free to join us if you are interested to learn more!
