Select an option

For the safety and management of the CESAR Observatory it's essential that any visit to the site is registered on the "Visitors Registration system" in the entrance hall of the tower building. Planned visits to the site should be announced beforehand in the agenda or to the Site Manager. If you want to install new instruments and/or want to use the facilitities on site for a (temporary) new experiment you need to be a registered user.

The Wbp law does include the following exception: the personal data can be used for criminal investigation if someone uses the site for making criminal offenses or statements.

Instrumentation (under test)

Any instrument and related units like ICT systems, installed and operated at the CESAR Observatory, either permanent or temporary, must be registered in CESAR Instrumentation database. You need an account to access this option. A registered instrument is owned by a registered user and can be allocated to a 'Measurement Setup' by this user. A user can share a registered instrument with other users. Users must first discuss any new instrument installation or (significant) changes in an existing installation with the site manager. Supplying the requested information in an instrument form doesn't imply automatically permission to install the instrument.

Registered users can submit online the details of the Measurement Setup and related Instruments to the Instrumentation database using the above menu link 'Instrumentation'. A Users Guide is available, click here to download (pdf)

Measurement Setup and Instrument registration are only available for users that are logged in!
