Description

The RSLC workflow (focus.py) can accept multiple input L0B files and takes care to process the data to a common set of center frequencies, polarizations, and bandwidths. However, as pointed out in the review of #373 it's not clear what happens when no valid mode intersection exists. I expect the script crashes somewhere, but it'd be nice if there was an explicit check and clear error message.
