ACS-HRC-MOSAIC-LINE pointing patterns
This is a one-dimensional (shift in y only) mosaic pattern, with the following allowable parameter ranges:
Pattern_Number: 1 Pattern_Type: ACS-HRC-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 sky (a DSS image of a galaxy) in the graphic above. The Visual Target Tuner (VTT) was used to make this graphic.
The default pattern is actually just the first 2 (leftmost) pointings in the VTT graphic above.
Pattern_Number: 25 Pattern_Type: ACS-HRC-MOSAIC-LINE Pattern_Purpose: MOSAIC Number_Of_Points: 2 Point_Spacing: 24.130 Line_Spacing: 0. Coordinate_Frame: POS-TARG Pattern_Orient: 90.0 Angle_Between_Sides: N/A Center_Pattern: YES
POS TARG equivalent: 0.000, -12.065 0.000, 12.065
