The missing coverage in antenna.py & simsetup.py will be fixed when the next pyuvdata version is released.

[steven-murray]

@bhazelton should I wait until that version is out before re-reviewing?

[bhazelton]

@steven-murray no, I'd rather not because then we'll have a period, even if it's short, where pyuvsim doesn't work with the newest pyuvdata. I could add pragmas to exclude those lines from coverage, but it feels a bit silly. I'd rather just take the coverage hit for a little while. This PR explicitly works with both the older and the newer versions, it's just that code specific to the newer versions isn't being hit because we install pyuvdata from conda not from the repo.
