On this page we provide links to software which can assist you when using SALSA.

Data analysis software

In this section we provide links to software which can be used to view and analyse the data yor obtain from SALSA.

SalsaJ is a program written within the EU-HOU project to view both spectra and images. A version known to work with the FITS-files (made after 2015-06-23) from the SALSA telescopes can be found here. Note: SalsaJ software requires that you have Java (free) installed. Documentation for how to analyse SALSA data using SalsaJ can be downloaded in English and in Swedish.

SALSA with MATLAB: The SalsaSpectrum class
SalsaSpectrum is a toolbox, written in the popular MATLAB language, which can be used to analyse data from SALSA. It is possible to analyse large numbers of spectra simultaneously, and to easily plot the results. SalsaSpectrum is written as a MATLAB class file, and therefore a Matlab installation is required to run it. Download the code here (right-click "Save-link-as"), and English documentation here. Note: the software is tested on Matlab version R2015a, but should also work on other versions. Further note that archival FITS-files taken with SALSA before 2015-06-23 cannot be analysed with the latest Matlab code, instead please use this older version for these fits files.

Other useful software

In this section we provide links to non-"data analysis" software which you may find useful.

The free planetarium software Stellarium, available at, can be used to predict the night sky visible with SALSA in the future.  Tell the program that you are in Onsala (or in Kungsbacka, which the program knows about and is close enough to Onsala), and select a date and time.  Note that you can enable coordinate grids within Stellarium: both Galactic and Equatorial coordinates are supported.

While most user should be able to connect to the SALSA computers using a webbrowser, one can also use the free remote desktop client ThinLinc to connect to the SALSA computers. The software works on Windows, Mac and Linux and is available here from Cendio. When using the ThinLinc software to connect to SALSA, enter "" or "" in the field "Server" and use your username and telscope password.
