FOCAL_PLANE
Focal plane coordinates: Position on a 2-d planar approximation to the focal plane (x,y mm).
The origin and orientation may be defined by the camera team, but we strongly recommend that the origin be on the optical axis and (if using CCD detectors) that the X axis be aligned along CCD rows.
- Note
Location and orientation of detectors are defined in a 3-d version of
FOCAL_PLANE
coordinates (the z axis is also relevant). Rectilinear x, y (and z when talking about the location of a detector) on the camera focal plane (mm). For z=0 choose a convenient point near the focus at x, y = 0.
