VLT/SPHERE

ascl:2009.002

Information

This repository provides tools for the reduction of VLT/SPHERE data. The pipeline currently provides support for processing IRDIS dual-band imaging (DBI), IRDIS classical imaging (CI), IRDIS long-slit spectroscopy (LSS) and IFS data. IRDIS dual-polarimetry imaging (DPI) and ZIMPOL are not supported at the moment.

If you find a bug or want to suggest improvements, please create a ticket.

Requirements

The pipeline requires official ESO pipeline for SPHERE to be installed and in your path. If the esorex command is not available the pipeline will output an error.

The package also relies on usual packages for data science and astronomy: numpy, scipy, pandas, matplotlib and astropy.

Installation

The easiest is to install sphere using pip:

pip install vlt-sphere

Otherwise your can download the current repository and install the package manually:

cd SPHERE-master/
python setup.py install

Examples

The package is not fully documented, but examples are provided.

Credits

Please cite the following reference if you use this pipeline in a scientific publication:

Moreover, the development of the SPHERE instrument has demanded a tremendous effort from many scientists, who have devoted several years of their life to design, build, test and commission the instrument. To recognize this work, we kindly ask you to cite the relevant instrumental papers in your scientific work. The reference papers for the instrument and its observing mode are:

SPHERE:

IRDIS:

IFS:

We are grateful for your effort, and hope that these tools will contribute to your scientific work and discoveries. Please feel free to report any bug or possible improvement to the author(s).
