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.
