Additional release of in-house reprocessed VIMOS images as part of the UK in-kind reprocessing project

Published: 15 Jan 2019

All VIMOS imaging science observations from April 2016 until the end of VIMOS operations in March 2018 have now been processed by ESO and are added to the VIMOS imaging data release. The latest release consists of 466 images and extracted source catalogues at the observing block level in Multi-Extension Fits (MEF) files, with a total size of 51.73 GB. The full VIMOS imaging collection of science data products consists of 38,100 frames with a total size of 1.9 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. The image products come with a variance map that was propagated through the complete reduction cycle. In addition, the data release contains confidence maps and associated single band source lists.

These science products are now published via the ESO Science Portal and they can also be downloaded via programmatic access. More details about data processing, the content of the source lists, data quality, astrometric and photometric calibrations are available in the associated Phase 3 data release description.
