This is a one-dimensional mosaic pattern, with the following allowable parameter ranges:

     Pattern_Number: 1 
       Pattern_Type: ACS-WFC-MOSAIC-LINE
    Pattern_Purpose: MOSAIC
   Number_Of_Points: 2-9
      Point_Spacing: 10.0 - 130.0 (arcseconds)
       Line_Spacing: 10.0 - 130.0 (arcseconds)
   Coordinate_Frame: POS-TARG
     Pattern_Orient: 0.0 - 360.0  (degrees)     
Angle_Between_Sides: 0.0 - 360.0  (degrees) 
     Center_Pattern: ?            (YES or NO)
The following versions of this Pattern_Type are projected onto the detector pixel space in the graphic above.
The default pattern is a compromise between increasing the field-of-view (to ~200x300 arcseconds) and covering the interchip gap -- all with the same guide stars.
