2. Observations

The observations consist of five I band images of PG 1115+080 with a typical seeing of 0:006-0:007. Using SIS, the tip-tilt adaptive optics camera installed at the Cassegrain focus of the CFHT, two 600s exposures were taken on the night of 1995 December 27. The detector was a Loral 3, 2048 [FORMULA] 2048 pixel CCD (pixel scale 0:000865). In addition, three I band frames were obtained at the NOT in direct imaging mode. Two 200s exposures were taken on the night of 1996 June 7 and an equivalent exposure was obtained on 1996 June 10. The Brocam2 2048 [FORMULA] 2048 CCD camera was used (pixel scale 0:001071).
