The ACS Associations Project is aiming to provide combinations of exposures from the Hubble Space Telescope Advanced Camera for Surveys (ACS) similar to those already produced for the older WFPC2 camera. The goal is to associate exposures of a region in the sky with as few restrictions as possible, e.g., regardless of time, science goal or principal investigator of the original observational programmes. Tests on an initial prototype for the ACS Associations are being carried out in order identify methods that will lead to the most interesting science product. Several ways of matching or cross-correlating the science frames, to find their relative shifts and rotations and then correct the astrometric information in the image header world coordinate system (WCS), are being tested against each other and the most stable and effective way of stacking the frames is being sought. At this stage there is also a good opportunity to revisit the implicit assumptions carried over from the WFPC2 Associations and find ways of breaking up the paradigms to allow for more flexible and potentially more useful associations. The association discovering algorithm has been made more complex and the possibility of offering user-defined on-the-fly associations with association strategies matching a user science goal is also being investigated.
