Freia for Observers

Freia is a standalone IRTF linux workstation with limited guest user accounts. Observers can request a temporary guest account to reduce their SpeX or iSHELL data using Spextool. This could be useful for those without access to IDL at their home institution, for example.

Freia guest user accounts are good for 2 months. Accounts are then offered to others waiting. They could also be renewed on request. Otherwise, guest user files are wiped at the end of the access period.
