"When computing eps (the central-obstruction fraction) for the annular Zernike fit, the code divided by the full diameter instead of by the reduced (Reduce Aperture) aperture that the fit is actually applied over."
"m_annularObsPercent (annular obstruction fraction) was computed as annularDiameter / diameter, using the full mirror diameter as the denominator. But the annular Zernike fit itself is normalized to the reduced aperture (m_clearAperature, set via Reduce Aperture), not the full diameter — so the eps fed into the fit didn't match the aperture the fit was actually running on."
