For sources at intermediate ecliptic latitude the annual range of variation of PA will be between these two extremes. This plot was generated for a potential launch in early 2008; it remains valid though for any launch date.
10.4. The position angle variation for PACS for an object at an ecliptic latitude of 59.5 degrees, close to the point of permanent visibility. The horizontal position is PA=000 degrees. The plotted positions of the PACS imaging detectors are for 2008 March 31st (start of visibility window) PA=127.4 degrees, 2008 June 15th (mid-window) PA=054.6 degrees, 2008 September 10th (end of visibility window) PA=333.7 degrees.
