摘要：

The long wavelength spectrometer (LWS) on-board the European Space Agency Infrared Space Observatory (ISO) uses a grating and one of two Fabry-Perot interferometers to make medium (lambda/Delta lambda similar to 200) and high (lambda/Delta lambda similar to 10000) resolution spectroscopic observations in the 43-196.9 mu m wavelength range. The instrument has been in continuous use since the launch of ISO in November 1995. In this paper we describe the calibration of the instrument and its performance, both spectroscopic and photometric, over the two years of instrument operations.
