On this page you can

• either upload a previously downloaded config file
• or enter your source information and select an instrument

Please note that the instrument links on the left lead to the home-page for that instrument. Press the "Select" button to actually select the instrument of your choice.

The source information consists of

1. the source type (point source / extended)
2. an eventually known redshift
3. the band we should use for renormalizing the template spectrum used for input
4. the magnitude and roughly the spectral type of your source
5. the template spectrum we should use as input.

Please note that the magnitude for extended source should be given per square-arcsecond.

In case you do not know which template to use, check the Overview and for a detailed comparison of two templates use the Compare Templates page.
