Quality Control and
Data Processing

Science data reduction

The QC group processes a stream of science-grade data products for selected VLT instruments. They are created using certified pipelines and certified master calibrations. Find an overview of the current streams here.

MUSE science products

MUSE science data products, processed as Internal Data Products by the Quality Control Group at ESO, are available covering the entire data history. They can be downloaded from the phase3 archive interface.

The MUSE science data types are identified by the DPR TYPE keyword of the FITS headers. Find information about the general MUSE data format here. The information

The SCIENCE further split into two different observing modes: Wide Field Mode (WFM) and Narrow Field Mode (NFM, commissioned in 2018). The WFM observations can be taken with Adaptive Optics system (AO) or without (NOAO). The NFM data are only taken with AO.

Processing of MUSE science data is done in few steps, using different recipes at each step. To obtain final product, all processing steps have to be applied.
