Abstract

The Infrared Space Observatory (ISO) had a scientific payload of four complementary instruments, a camera, a photometer, and two spectrometers. Two instruments, the Long Wavelength Spectrometer (LWS) and the Camera were able to operate in parallel mode i.e. taking scientific data while another instrument was active. The LWS had ten detectors which allowed simultaneous coverage of the entire 43-197 micron range. In parallel mode the diffraction grating remained in a fixed position allowing the spectrometer to act like a 10 channel photometer with bandwidths of 0.3 microns (one resolution element in second order) for the five short wavelength detectors and 0.6 microns (one resolution element in first order) for the five long wavelength detectors. This paper describes the LWS parallel mode and gives details on the data was obtained. The paper will also describe the automated processing developed for the parallel mode data and the calibration strategy employed. The parallel data has very good sparse coverage in the Rho Oph region and a temperature map derived from the parallel mode data are presented.
