- Common functionalities: a description of all the basics actions that can be performed in most CASSIS windows
- Databases: explains how to choose a database and how to create and manage templates
- Interoperability: CASSIS in the Virtual Observatory world!
- Scripts: some information about scripting
- Caveats and tricks: a list of encountered problems and how to solve them

Starting CASSIS and displaying a spectrum
To start CASSIS:
- if you installed the desktop version :
from a x-term, go to the cassis directory and type: ./cassis.run xxxx, where xxxx is the size in mega bytes
of the memory you want to allow to CASSIS (e.g., 1024, 2048, etc).
Just typing ./cassis.run, CASSIS will use by default 1 Gb of memory.
Warning : at the first launch, CASSIS may take a few minutes to setup. - if you chose the online version, just click on this link: http://cassis.irap.omp.eu/online/cassis.jnlp
When launched CASSIS opens its main window:
Cassis 5.0 - database from yyyy (name_of_the_database),
or
Cassis Online - database from yyyy (name_of_the_database),
where yyyy is SQLITE or VAMDC (see the section 4 for more details).
You can then start using CASSIS. For example, to display the CO spectrum which comes with CASSIS, follow these steps:
- open the Spectrum Manager (Modules > Spectrum Manager or click on the icon )
- click on "Open local resource"
- by default, you should be in CASSIS folder > delivery > data (if not go to this directory)
- select "CO.bas"
- click on "Display spectrum"
You can also load data via one of the views or modules described in Section 3.
For a quick access to the modules and to some utilities, you can use the icons:
Icon | Equivalent in menu bar | Description | More info |
---|---|---|---|
File → Open | Opens a window to browse for a data file ; CASSIS will open the file with the spectrum manager for inspection before display. | ||
Modules → Spectrum Manager | Opens the Spectrum Manager | § 2.1 | |
File → Save | To save the displayed spectrum/spectra in one of the following formats: pdf, png, votable, fits, fus (full spectrum only), lis (line spectrum only), rot (rotational diagram only). | ||
File → Print | To send the current plot to a printer. Warning: currently does not work under Mac OS 10.9 and from the Line Spectrum tab (all OS) | ||
Modules → Spectrum Analysis | Opens the Spectrum Analysis window. | § 2.2 | |
Modules → LTE+RADEX | Opens the LTE+RADEX Analysis window. | § 2.3 | |
Modules → Loomis Wood | Opens the Loomis Wood Analysis window | § 2.4 | |
Modules → Line Analysis | Opens the Line Analysis window | § 2.5 | |
Modules → Rotational Diagram | Opens the Rotational Diagram window | § 2.6 | |
