Getting Data from CDAW Example Part 2

I’m looking at this code here:

solo_mag = TimeSeries(downloaded_files, concatenate=True)
solo_mag.peek(‘B_RTN_1’ , ‘B_RTN_2’ , ‘B_RTN_3’)

Where can I find a full list of variables available for the peek function? Is it only B_RTN_

Can you provide more context?

I was under the impression that peak doesn’t take arguments.

I’m all over the place then. So what does B_RTN_1, B_RTN_2, etc represent? I can’t seem to find documentation on it

I’ve not used the data myself, but I would at a guess think that they would be the names of the variables within the timeseries.
