Overview
Using Google Analytics custom filters, traffic from the Catchpoint nodes can be excluded so you can just view data from other sources. This can be accomplished by filtering based on the User Agent string sent by all Catchpoint nodes. This method of filtering is more effective than filtering by IP, because the Catchpoint Last Mile and Wireless node IPs are dynamic, meaning they change all the time, so any IP-based filters would have to be edited frequently.
How to do it:
Select Custom filter, Exclude, and then Browser Version in the Filter Field dropdown menu. Since all Catchpoint requests include "Catchpoint" in the User Agent string, you can match them using the regular expression .*(Catchpoint).* as in the screenshot below:

Please note it may take as long as 24 hours before filter effects become visible in your data.
*Another way to block analytic tags is to block the requests from being made within Catchpoint by using Request Overrides.
