INSTRUMENTAL STRAY RADIATION

 

Due to the particular characteristics of each of the instruments and detectors other sources of stray radiation have to be considered when designing observations. These effects have been found in-orbit and are under detailed investigation. The Addenda of the OBSERVER'S MANUALS give descriptions and how these affect observations

• Fringing (ripples in the spectrum) in LWS and SWS
• Artifacts in some of LWS spectra
• Ghost images and memory effects in CAM
• Straylight on the fine calibration source in PHT (see section on photometric accuracy)
