... The GHRS has the usual components of an astronomical spectrograph: entrance apertures, a collimator, dispersers, camera mirrors, and detectors. ... The collimator and camera mirrors are unexceptional and need no further description here (see ``The HST Focal Plane and the GHRS Apertures'' on page 73 for details). ... The first two first-order gratings, G140L and G140M, have their spectra imaged by mirror Cam-A onto detector D1, which is optimized for the shortest wavelengths. ...

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...
