A data release has been published containing science data products from all science observations using the VIMOS instrument in imaging mode, from the beginning of regular operations in April 2003 until August 2015. The remaining data will be added in the near future. All image products were produced at the observing block level and no attempt was made to stack data between observing blocks. The image products come with a variance map that was propagated through the complete reduction cycle. These science products are now published via the ESO Science Archive Facility.
Pipeline-Processed VIMOS Images
Published: 18 Apr 2018
The science products for this release were processed by the Cambridge Astronomy Survey Unit (CASU). The release consists of 37,168 science frames in Multi-Extension Fits files with a total size of 1.85 TB. Science frames are astrometrically and photometrically calibrated. The astrometric solution has been computed using 2MASS catalogue stars in the science fields, while the photometric calibration was done using zeropoints from matched VIMOS standard star images. In addition, the data release contains confidence maps and associated single band source lists.
The VIMOS images and source lists can be queried and downloaded using the Phase 3 generic query form that provides access to all Phase 3 data, or via the Phase 3 query form dedicated to imaging data with query parameters suited to harvest imaging data.
More details about the data processing, the content of the source lists, the data quality, and the astrometric and photometric calibrations are available in the associated Phase 3 data release description.
