This page holds mask files that may not yet be included in a CAT release. Guidance on how to use these can be found on the Adding masks to CAT page.

If no mask files are present then currently all mask files are included in the latest release of CAT.

If you are running the latest release of CAT / Paragon-neo, and the mask file you require is not present, if your instrument has a valid CSS Agreement, then you can raise a ticket in our Service Desk with details of the mask requirements.
