Question: scripted interface - set rest frequency?

[keflavich]

Is there a way to set the rest frequency in the scripted interface? e.g.

await app.appendFile("file.fits")
await app.setRestFrequency('150GHz')

I didn't find any documentation on this; I'd be perfectly happy to be pointed at appropriate documentation if it exists.

Just looking at the code for the rest frequency section (I didn't write it, so perhaps @YuHsuan-Hwang has more insight):

const frame = await app.appendFile("file.fits");
frame.restFreqStore.setCustomUnit("GHz");
frame.restFreqStore.setCustomVal(150);

I'm looking at the rest frequency store code here

Yes, this should work

Thanks! This is really helpful. I think this would be a great example to add to the docs somewhere.

I think for those accustomed to using the console, this also shows how one would discover more editable attributes - I didn't know that you could store the result of app.appendFile in a frame variable, for example.
