Peering into the Dust: News from VISIR
Abstract
VISIR - ESO's VLT Imager and Spectrometer for mid-InfraRed - is a combined imager and echelle spectrograph, providing access to the atmospheric N and Q-band windows (7.7-13.3 and 16-24 μm) with a great variety of observing modes. Starting in Period 81 a new set of filters is available to the users of VISIR, and the characteristics of the filters and their science verification are described. The installation of the filters is the most visible result of a technical intervention performed at Paranal between April 24 and May 8, 2007, however more upgrades were also performed.
