ADONIS Data Reduction

ECLIPSE data reduction package
IDL data reduction scripts
IDAC - PSF deconvolution package

Note: No data transfer is permitted from the ADOCAM computer during observations.

ECLIPSE data reduction package

ECLIPSE is an ANSI C library offering services dedicated to astronomical data processing with emphasis on infrared and visible images and spectra. ECLIPSE version 3.8-1 is distributed under the Scisoft Astronomical Software Collectionwhich is installed on all La Silla machines.

More information about ECLIPSE, including downloads and user guides, can be found at the ECLIPSE Home Page.

Note that in addition to installing the ECLIPSE main package, you will also need to install the ADONIS instrument package.

ECLIPSE Pipeline for Adonis data

A pipeline for basic data reduction of ADONIS data has been developed by F. Marchis and D. Le Mignant. The data routines include ECLIPSE commands and additional C-Shell scripts. A detailed description of the pipeline procedure is available on-line.

Note that the ECLIPSE Pipeline only works under an earlier version of ECLIPSE (version 3.4).To install this version you will need to download the files: eclipse3_4.tar.gz and ScriptAdonis.tar. Unpack the tar files and follow the instructions in the README and INSTALL files.

Currently Eclipse-3.4 is the default version for w3p6drs (3.6-m control room) and drl4 (3.6-m astronomer office). To switch to the latest version (Eclipse-3.8-1) you must uncomment the set path command in the.cshrc file.
E.g.
#set path = (~/bin/eclipse/bin ~/bin/eclipse/scripts ~/bin $path)

Note: All computers in the user's room at La Silla will have the latest verison of eclipse installed.

If you use the Eclipse Pipeline for your ADONIS data, kindly acknowledge the authors in any subsequent articles.

IDL data reduction package

An Adonis Reduction Package using IDL has been developed by E. Pantin. This package is intended to reduce ADONIS SharpII data. It allows the same operations as the ECLIPSE package as well as some useful graphical routines to display data cubes.

To run this package you must first have IDL software installed on your machine and all of its libraries, including the ASTROLIB library. Then download the file PACKAGE_IDL_ADONIS.tar.gz (4 Mb). Unpack the tar file under your home directory and refer to the short Manual.

If you use IDL routine for your ADONIS data, kindly acknowledge the author in any subsequent articles.

IDAC myopic deconvolution

IDAC, (Iterative Deconvolution Algorithm in C), is a flexible non-linear deconvolution algorithm which uses an error metric minimisation scheme (by means of a conjugate gradient search) to reconstruct an object distribution when the point spread function (PSF) is either known, i.e. fixed, or poorly determined, i.e. blind. It will work either with a single observation or with multiple observations of the same object.

More information on IDAC, including the latest downloads, can be found at the IDAC Home Page. New

For the users we have prepared (2.5 version only)

Blind deconvolution, might also be used. It is a technique for the extraction of the PSF and the object, when no knowledge of the PSF is available.

A complete description of the deconvolution method and some results obtained on real ADONIS data can be find in the following article:
