Document ALMA antenna configuration #46

Closed cvoegele closed 2 years ago

cvoegele commented 2 years ago

The ALMA configuration should not have this many antennas. This needs fixing.

Devin Crichton Today at 3:13 PM Regarding the presentation, why does ALMA have antennas and stations? 12 replies

Marc Audard 2 hours ago If I may intervene here, perhaps to help, not sure I understand the question.

Rohit Sharma 2 hours ago Yes, that is one issue we need to sort it out. So, there is only one station.

Marc Audard 2 hours ago OK, as I am not involved I may not catch the issue. ALMA has many antennas with many stations, with the goal of having different configurations.

Devin Crichton 2 hours ago To clarify the question, it looks like ALMA is being simulated like an SKA-low-like system but with the ALMA array layout for stations.

Mark Sargent 1 hour ago Stations = antenna foundations (there are 192 of them, which can accommodate the 66 antennae in a range of different configurations) :+1: 1

Devin Crichton 1 hour ago Yeah, but the image had the orange points as stations with many blue antennas per if I saw correctly.

Mark Sargent 1 hour ago Would you be able to post the image here?

Christoph Vögele 1 hour ago Of course. I have the image here. It may very well be it needs fixing. alma.png alma.png

Rohit Sharma 1 hour ago Yes Devin, at the moment the implementation of a dish is equivalent to a station with one antenna with modified beams. (edited)

Devin Crichton 1 hour ago Ok, so that's not a grid of antennas per station, just one.

Devin Crichton 1 hour ago (Sorry I think there is some overlapping terminology here, I assumed the SKA-low terms since OSKAR is being used)

Rohit Sharma 1 hour ago The terminology is explained here: https://ska-telescope.gitlab.io/sim/oskar/telescope_model/telescope_model.html

sfiruch commented 2 years ago

We can clarify this in the documentation.

sfiruch commented 2 years ago

@rohitcbscient any updates on this?

rohitcbscient commented 2 years ago

The documentation needs to be updated. Not done yet. I will do it.

sfiruch commented 2 years ago

Manual is here https://i4ds.github.io/Karabo-Pipeline/development.html#update-documentation

rohitcbscient commented 2 years ago

A brief readme for telescope directory structure is added.
