Useless without:
- numerical values for wavefront P-V and RMS error and Strehl;
- the telescope serial number, and ideally...
- a photograph of the actual scope tested with its serial number visible.

A recent thread on CN recently with a link to a russian test lab also showed that it appears some suppliers are cloning and issuing test reports just adding the scope serial number and date. This only became evident when russian lab noticed test certificates that matched those submitted with scopes tested previously, and also noticed the wavefront errors when tested did not resemble that in the test certificate.
