The selection of the desired AOT parameters is made from the "Observation" menu. The Herschel and Instrument Observer's Manuals are your primary reference for information about using the Herschel instruments and selecting the appropriate AOT parameters. Additional comments about the AOTs are provided in Chapter 8, Entering An Astronomical Observation Request (AOR), Chapter 10, Astronomical Observation Templates (AOTs) , Chapter 11, PACS AOTs, Chapter 12, SPIRE AOTs and Chapter 13, HIFI AOTs of this Guide. There are nine Herschel AOTs fully implemented in HSpot. Each AOT has several options as to the mode of operation (e.g., reference source, array choice or spectrometer resolution).
