BPA
Type: Adverb  (Real)
Use:  The position angle in degrees of an arbitrary component.
      It is usually measured North through East or counter-
      clockwise with zero degrees pointing up.
Null value:   0
      Null value usually simply used as 0.0.
Verbs:
   ADDBEAM.......Inserts clean beam parameters in image header.
