SMOV3b Check of the WFPC2 Point-Spread-Function

-V. Kozhurina-Platais, L.M. Lubin, and A.M. Koekemoer

We examine the Point-Spread-Function (PSF) of the WFPC2 after the Servicing Mission 3b using dithered observations of the rich globular cluster, Omega Cen. Comparisons to previous measurements of the PSF which were made after the last two servicing missions (SM2 and SM3a) indicate that no significant variations in the PSF have occurred. We also present an analysis of the shape of the PSF as a function of five positions on the Planetary Camera (PC) chip.
