Detailed Description

Convert between distorted focal plane and detector coordinates.

This base class is used to convert between distorted focal plane coordinates (x/y) in millimeters and detector coordinates in pixels. The class expects to find a set of coefficients in the naif instrument (or instrument addendum) kernel that describe the transform from detector to focal plane and vice versa. The transform from detector to focal plane is:

x = transx[0] + sample * transx[1] + line * transx[2];
y = transy[0] + sample * transy[1] + line * transy[2];
where, transx and transy are the coefficients from the naif kernel.
The should be in the form of:
INSxxxxxx_TRANSX = ( a, b, c)
INSxxxxxx_TRANSY = ( d, e, f)
where, xxxxxx is the NAIF instrument id code.

Likewise, the inverse transform is:

samp = itranss[0] + x * itranss[1] + y * itranss[2];
line = itransl[0] + x * itransl[1] + y * itransl[2];
where, itranss and itranss are the coefficients from the naif kernel.
The should be in the form of:
INSxxxxxx_ITRANSS = ( a, b, c)
INSxxxxxx_ITRANSL = ( d, e, f)
where, xxxxxx is the NAIF instrument id code.

NOTE: This is detector (sample, line) not necessarily image (sample, line). If the image was reformatted from what was collected the two differ. See the New Horizons LEISA camera for an example (LEISA is a frame camera being treated as a line scan camera).

This method will compute both the centered and normal detector position given a distorted focal plane coordinate.
