AB: The two SECCHI instrument suites aboard the upcoming STEREO mission include the COR2 coronagraphs which observe the middle/outer corona; namely, from 2.5 to 15 solar radii. As of the end of August 2004, both COR2 instruments have been assembled and delivered to the SECCHI project and their perfomance has been measured and analyzed. The coronagraphs have met (and in some cases, exceeded) their performance requirements. Here, we present in detail the results of the calibration (photometry, polarization, stray light levels, etc) of the COR2 coronagraphs. We compare these new coronagraphs to the LASCO ones and discuss how they will contribute to the scientific success of the STEREO mission.
