The enclosed energy diagram shows that throughout most of the FOV CIRCE reaches enclosed energy values > 80% in the J-band. Pixels in the corners of the image contains 70%. The 0.10 arcsec plate scale provide seeing limited images with less than 0.25'' intrinsic FWHM. The following spot diagram show aberrations of the image along the field of view for the cleared mode. These aberrations do not contain the signature of chromatism.
