1.1 Purpose

The LWS Handbook is one in a series of five1.1 documents that explain the operations of the Infrared Space Observatory (ISO) and its four instruments, the data received from the instruments and the processing carried out on the data. Volume I gives an overview of the entire ISO mission and it explains the operations of the ISO satellite while the remaining four explain the individual instruments (CAM, LWS, PHT and SWS). The LWS document is intended to provide all information necessary to understand the offered LWS standard data products, as processed by Version 10 of the Off-Line Processing (OLP) system, retrievable from the Legacy ISO Data Archive (IDA) at:

https://www.cosmos.esa.int/web/iso

Therefore, it gives a full description of the instrument, the automatic processing pipeline, the calibration steps applied and the data products. In order to further reduce data through interactive analysis there are two software packages available with reduction tools written in IDL. Links to these are provided in Chapter 8.

This volume of the ISO Handbook serves as the reference for both the processing as well as the correct interpretation of LWS data as available from the ISO Data Archive.
