Hi Conor,

Thanks for the chat at ELC and clarifying what was said here on the
list.

Regarding these masks and their width, they are indeed wide but they
determine what to match against, and we have no reason to match anything
except the exact number.

This was previously shortly discussed here, and clarified by Rob:

I'll be sending a v3 of this with only the camera patches soon.

Kind regards,
Ernest
