Introduction

The purpose of this section is to describe the data product of the VIS processing function. The description present in this section corresponds to the version of the VIS pipeline used for PV phase. For the moment the VIS PF runs in CCD mode (Data model 9.0) , an upgrade is ongoing to run in quadrant mode (Data model 10.0).

The VIS processing function produces two types of data products: images and catalogues together with calibration data. These are produced for both calibrated individual exposures and stacked images. In addition, there are auxiliary pixel data products associated with each of these images: noise map and Flagmap. For stacked images, overlapping images are combined to produce contiguous sky coverage at each survey pointing. The dither patterns used are defined in the mission database. These final products are delivered to other OUs (MER-SHE-NIR).
