This primitive sets the origin of an observation, including all integrations, using the ORAC_X_LOWER_BOUND and ORAC_Y_LOWER_BOUND user headers in the frame. It is needed to correct the raw data from a sub-array for which the origin is still at the default. If either header is undefined, the primitive creates a default origin (1,1). The origin is not set if ORAC_X_LOWER_BOUND does not exist.

• This primitive is suitable for UFTI, IRCAM, and Michelle and UIST in imaging mode.

KAPPA: SETORIGIN.
