The goal of this blog is to become a dynamical way of providing fast and updated useful information, to the user of the instrument OSIRIS at GTC, complementing the information provided by GRANTECAN S.A.
It contains information about the manuals, instrument calibration, pipelines for download, tutorials, contributions, announcements, etc. Also, some historical information about the integration, and commissioning of the different observing modes is provided as well.
This Blog is maintained by the OSIRIS Scientific Team.

La estructura (I)



El concepto estructural de OSIRIS está basado en un banco óptico 3D que soporta todos los elementos ópticos a excepción del colimador. Características generales (en inglés):
The OSIRIS mechanical design is driven by the stringent top level requirements of alternative use in both Cassegrain and Nasmyth focus, large optical components, image stability during one hour better than ±7.2micro-meter in imaging mode and ±3.6 micro-meter in spectroscopic mode at the detector focal plane (with a goal of ±3.6 micro-meter and ±1.8 micro-meter respectively) and a flux variation through the long slit less than 3.7% during all the night.

La estructura ha sido fabricada por TTM (Valencia).
