OVERVIEW OF OBSERVING MODES AND AOTS

 

For historical reasons the AOT numbers are not consecutive. The first column gives the AOT identifier, the second the AOT title and the third column gives the restriction for the AOT if applied to observations of solar system targets (`not applicable' means that this AOT may not be used for solar system observations, `single pointing' means that no raster maps may be performed, `staring' means that the chopper may not be used and `one entrance aperture' in the case for SWS AOTs means that change of wavelength is not allowed when it involves an automatic change of the entrance aperture.

Polarisation observations with ISOCAM and ISOPHOT will be implemented in operations by a different route than that for the standard ``AOT-based'' observing modes; from the point of view of proposers, there will be no difference in the procedure to enter polarisation observations until after the end of the Phase 1 review by OTAC.

Unreleased AOTs as of 26 July 1996.
