9.1 Introduction

This chapter discusses several instrumental effects that have not been discussed elsewhere in this handbook. Most of them are caveats the users should be aware of related to known limitations of the automated pipeline processing of SWS data products. Some of them can be properly accounted for through manual processing using Interactive Analysis software (OSIA or ISAP) while for some others there is currently no correction available. A full list of comon calibration concerns is given in Table B.1 of Appendix B. Section 9.2 discusses transient (or memory) effects in the SWS detectors of bands 2, 4, 5 and 6. It also discusses reference scans and glitch tails. Section 9.3 discusses two forms of detector jumps. In Section 9.4 some remarks are made about the consequences of having (small) apertures of different sizes. Section 9.5 discusses the influence an observation with CAM CVF could have on a subsequent SWS observation. Section 9.6 discusses the influence of the diffuse background of the spectra. The last Section 9.7 discusses fringes and the probably related issue of baseline ripples.
