The Wide Field Astronomy Unit archives optical/near-infrared imaging data from UKIRT/WFCAM, VISTA/VIRCAM and VST/OMEGACAM. The current data structures are based on independent detections in each bands, but there are many science cases where forced photometry in all bands (and indeed on images from other datasets) are necessary to get the precision necessary to fit models, or to give upper limits on non-detections. However, many of the science cases given by PIs and others require a range of software to achieve the photometric accuracy, ranging from the CASU imcore_list for best point-source photometry to GaAP and LAMBDAR for improved extragalactic parameters. This poster will discuss the scope of the new pipeline and the data management structures that control it for the different use cases.
