Introduction

In collaboration with the various instrument consortia, the Pipeline Systems Department has undertaken to implement data reduction pipelines for the most commonly used VLT/VLTI instrument modes. These data reduction pipelines have three main purposes:

  • Data quality control - pipelines are used to produce the quantitative information necessary to monitor instrument performance (see the ESO Quality Control web pages for more information).
  • Master calibration product creation - pipelines are used to produce master calibration products (e.g. combined bias frames, super-flats, wavelength dispersion solutions).
  • Science product creation - using pipeline-generated master calibration products, science products are produced for supported instrument modes (e.g. combined ISAAC jitter stacks; bias-corrected, flat-fielded FORS images, wavelength-calibrated UVES spectra). The accuracy of the science products can be limited both by the quality of the available master calibration products and by the algorithmic implementation of the pipelines themselves. In particular, adopted reduction strategies may not be suitable for all scientific goals. Therefore, ESO assumes no responsibility for the usefulness of reduced data for any specific scientific project.

Pipelines Running Environments: Reflex, Gasgano and Esorex

Reflex is the recommended way to reduce ESO data. It automatically organizes input files according to their category and runs the entire reduction chain at the push of a button. It supports break points in the reduction sequence in order to inspect and interact with intermediate and final products and rerun the corresponding step if necessary. Please see this table for a list of the supported instrument modes.

Gasgano is a Java-based data file organizer developed and maintained by ESO. It can be used to manage and organize in a systematic way the astronomical data observed and produced by all VLT compliant telescopes. Gasgano is a graphics-based software tool for organising and viewing data files produced by the VLT Control System. Gasgano offers functionalities for data viewing, grouping, sorting, classification, searching, and filtering of data. And, of course, Gasgano will run any requested CPL recipe on the selected data.

Esorex, a command-line utility for running pipeline recipes is also available. It may be embedded by users at their home institute into data reduction scripts for the automation of processing tasks.

Both Gasgano and Esorex are included in the pipeline public release packages.

  • NOTE 1: Scientifically validated workflows are those that have been confirmed to produce science grade data products. All validated workflows are based on pipelines that have gone through an extensive end-to-end review
  • NOTE 2: This column indicates whether there is at least one workflow for that pipeline that includes an interactive component to adjust pipeline parameters

Pipeline Releases Based on the most Recent CPL Release

The Pipeline Systems Department makes also these data reduction pipelines available to the user community. The table below provides access to the pipelines currently available.

Installation of Multiple Pipelines

The procedure for a simultaneous installation of multiple pipelines on a single account is:
  • Download the desired pipeline kits from the "Release File" column in the table below into an empty, temporary directory.
  • Download the Pipeline-kit installer into the same directory.
  • If necessary, make it executable: chmod u+x install_pipelinekit
  • Execute the command: ./install_pipelinekit *-kit-*.*
  • After the installation the temporary directory with its contents can be deleted.

 

The below pipelines are delivered with CPL 6.4.1, gasgano 2.4.5 and esorex 3.10.2, they can be installed together using the above procedure.
