Common commands of Scisoft and Starlink

Scisoft includes a number of Starlink programs but not all. So perhaps someone (in this case me!) needs to run something that it is not included in the Scisoft (like DIPSO). So, nothing wrong to go on and install both. But in this case that someone has to be careful not to mix the commands. […]

Installing Starlink

Installing and running Starlink is pretty much straightforward. Firstly, get the latest release (Namaka, when this post was written) and extract the file wherever you want. Then select which shell you want to use and follow the post-installation run-up or the info given below (supposing it was downloaded and extracted in /home/user/soft/star-namaka/). Bash case: Open […]

Extracting spectra from AAOmega observations

AAOmega (at Anglo-Australian Observatory) observations can be reduced with 2dfdrv4 tool pretty much very easilly. But the reduction ‘s final output is a combined fits image which includes all spectra from the 400 fibers. So, the user has to extra by himself/herself the spectra individually and this has been frustrating (at least for me…). 1. […]

Figaro within Scisoft

Scisoft (7.5) includes also a number of shared programs available to use. But they are not immediately available when invoking Scisoft, like FIGARO, one of the programs provided with STARLINK. There are two ways to start FIGARO (both provided by Giannis K. at Computer Center support of Physics/Univ of Crete) : One is to use […]

Reading fits headers within Starlink (.sdf files)

Starlink has its own image format (the NDF format, .sdf extension) which is not perhaps so convenient as the fits format. Nevertheless, there are ways to read the contents of the fits headers of your .sdf files, depending on the program you are working with. With KAPPA you can use the command: $ fitslist file.sdf […]

40 characters limit in Starlink

When you install Starlink you have to determine the directory of the program (set env starlink_dir /path/to/software/star, in the ~/.tcshrc file). Then, any application runs under this directory. But, there is a limit in the number of characters used (only 40). This can cause some programs not to run at all or run very quickly […]
