Scientific paper

We present an improved solution for the geometric distortion in WFPC2, based on multiple observations of a rich stellar field. We also quantify the long-term variation of the relative position of the detectors by tracking the position of the K spots over time. We suggest possible avenues to develop an improved wavelength- and time-dependent geometric solution for WFPC2.
