IMARK

The IMARK command is part of the ASTERIX image processing system. One of its modes of operation enables an SSDS to be used as the source of celestial positions (thus enabling images with different orientations from that which was searched to be annotated). Control over the type and colour of the plot symbol can be exercised. For example,

   > ISTART my_pss_demo vws
   > IDISPLAY
   > IMARK MY_SOURCES SYMBOL=4 COLOUR=2
