INT CCD scales and orientations



Following orientations are as seeing in the DS9 display without rotation or flip.

For WFC, to match standard sky orientation in finding charts (that is North up, East left) DS9 display should be rotated as follows:
  • CCD1, CCD3 and CCD4: rotates 270 degrees (DS9 top menu -> Zoom -> 270 Degrees)

  • CCD2: rotates 180 degrees (DS9 top menu -> Zoom -> 180 Degrees)


IDS acquisition camera

Orientation
IDS-AG0
70x70
For sky PA=0: North right, East down
For sky PA=90: North up, East right

For IDS+Red+2 acquisition camera to match the standard sky orientation (North UP and East to the LEFT) in the DS9 it is necessary to rotate 90 and invert Y (DS9 top menu -> Zoom -> 90 Degrees & Invert Y) .
