Reflex: Scientific Workflows for the ESO Pipelines

Ballester, Pascal

The recently released Reflex scientific workflow environment supports the interactive execution of ESO VLT data reduction pipelines. Reflex is based upon the Kepler workflow engine, and provides actors for organizing the data, executing pipeline recipes based on the ESO Common Pipeline Library, invoking Python scripts, and constructing interaction loops. Reflex will greatly enhance the quick validation and reduction of the scientific data. In this paper, we address the design and usage of data reduction workflows on the basis of two examples for the UVES echelle spectrograph, and the HAWK-I near-infrared imager.
